Skip setup the snapshots app if the filesystem type is btrfs
but / is not a btrfs subvolume. For example, this may happen in
containers where / is a bind mounted btrfs filesystem.
Closes#1994
Tests performed:
- Install freedombox on a lxc container inside Pioneer-FreedomBox.
(In a container, / is a bind mounted btrfs filesystem). The snapshot app
setup is skipped.
- Install freedombox inside dev container (which uses btrfs filesystem
image). The snapshot app setup succeeds.
- Install freedombox inside container that uses a host directory as a base
and the filesystem is ext4. The snapshot app setup is skipped.
