[PATCH 6/7] busybox: support mount via label for btrfs and squashfs

[Andre McCurdy <armccurdy@gmail.com>]

Also move the mount via label (and mount via UUID) support into its
own config fragment and disable volume ID support for less common
filesystem formats exFAT and NILFS.

Following this commit, mount via label is supported for btrfs, ext, f2fs,
fat and squashfs.
