Bug#904086: Add fsck.xfs and xfs_repair to the initramfs

[Marcos Mello <marcosfrm@outlook.com>]

Package: initramfs-tools-core
Version: 0.130
Severity: normal

Default passno for XFS in fstab is 0:

https://salsa.debian.org/installer-team/partman-xfs/blob/63/fstab.d/xfs#L24

Because of this, fsck hook does not add fsck.xfs. Fine up to xfsprogs 4.15.1, since fsck.xfs does nothing.

However, starting with xfsprogs 4.16.0, fsck.xfs runs xfs_repair when called with -f (forcefsck|fsck.mode=force):

https://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git/commit/?id=7c3e94a3001292946521fb4cfac841e9ac32691b

So having fsck.xfs and xfs_repair in the initramfs is useful now. passno must stay 0 because verification is only done in force mode.

(xfsprogs is outdated in sid right now)
