The host's rootless Docker socket is mounted as /var/run/docker.sock
inside CI containers. Its data root is on the host filesystem (not
accessible from inside the container), so _get_docker_free_bytes
returns 0. Previously the code didn't trust this and started a local
dockerd on /dev/shm (too small). Now checks pgrep for dockerd processes
— if none found inside the container, the socket is the host's Docker
and should be trusted.

Add pgrep diagnostics before/after pkill to identify lingering dockerd
processes. If pkill fails and pgrep still finds dockerd, kill by PID
directly via os.kill. When inner dockerd can't be killed (still alive),
use /dev/shm as data root since the overlay is still full.

The inner dockerd started by the CI image doesn't respond to SIGTERM.
Use pkill -9 to force-kill it, then verify it's actually dead by
running docker info. If the old daemon is still alive (can't be killed),
use /dev/shm/docker.sock as an alternate socket path to avoid conflicts.
Also moved the data root cleanup after the kill verification, so we
don't delete files while the old daemon might still be writing to them.

/dev/shm is a 16G tmpfs — too small for the 505MB molecule-test-base
image. Use /tmp/docker-data on the container's overlay instead, after
killing the inner dockerd and cleaning up its data root to free ~2.4GB.
Also use the standard DOCKER_SOCK path (/var/run/docker.sock) for the
local dockerd, since the inner dockerd has been killed and the socket
is free.

When no socket has sufficient space, don't fall back to the low-space
inner dockerd (which will fail on image pulls). Instead, kill the inner
dockerd, clean up its data root to free space, and start a local
dockerd on /dev/shm with vfs storage driver.
Also adds pkill of the inner dockerd and cleanup of its data root
(overlay2, image, volumes, containers) before starting the local
dockerd, to free up the 2.4GB used by the inner dockerd's data.

The start_docker.py script was checking /var/run/docker.sock first,
which inside CI containers is an inner dockerd (v29.5.3) with data
root on the container's 38G overlay (often 100% full). When
_get_docker_free_bytes() returned 0 (data root path not accessible
from inside container), the script assumed it was the host Docker
with plenty of space and returned True immediately — without trying
the host's rootless Docker socket at /run/host-docker.sock.
Fix: try /run/host-docker.sock FIRST (before /var/run/docker.sock).
The host socket is mounted by the gitea runner config and has access
to the host's full filesystem (455G). Only trust free_bytes == 0
(= data root not accessible from container) for /run/host-docker.sock,
since the host's root dir is genuinely outside the container. For
other sockets (inner dockerd), free_bytes == 0 means the path doesn't
exist inside the container — don't trust it.

The CI container can't access the host Docker's data root
(/home/grm-ci-runner-X/.local/share/docker) to check disk space.
When free_bytes=0, the root dir is on the host filesystem (455G).
Always use host Docker in that case instead of starting a local
dockerd on the 16G /dev/shm tmpfs (which fills up with images).

The new dockerd can't create bridge network or ip6tables chains
(permission denied). Disable both — molecule tests use host network.
