[PATCH 24/40] guestsfs: ensure linux directory exists

[Luis Chamberlain <mcgrof@kernel.org>]

When 9p is enabled, guests need to access the host's linux directory
through the 9P filesystem mount. However, after the 9p build tasks were
moved to a separate subrole, the directory creation that ensures this
mount point exists was no longer happening before guest bringup.

This caused guests to fail during bringup when trying to mount the
non-existent linux directory via 9P. The issue manifests as mount
failures during guest initialization.

Fix this by ensuring the linux directory exists as part of the guestfs
bringup process, before any guests are started. This restores the
necessary ordering that was lost during the 9p task reorganization.

Fixes: d0d54b450b0d ("bootlinux: Move 9p build tasks to a subrole")
