Revert "snapcraft.yaml: enable unconfined mode in lxd-support interface"

This reverts commit 2f0fcab.

There are currently multiple issues with landing this change:

 * The snap store is not allowing uploads of snaps using this plug. See https://git.launchpad.net/review-tools/commit/reviewtools/sr_common.py?id=08e83bf8d0b36eb8ff82ae74e774f00d56493d5f
 * The Ubuntu kernel and/or the apparmor parser in Noble has a bug that is incorrectly confining LXD rather than providing unconfinement. See https://bugs.launchpad.net/apparmor/+bug/2067900

There are currently various proposals on the table on how to resolve this, but with no clear timeline.

Once it is resolved we can try and land this again.
