[PATCH 2/3] common/rc: move XFS-specific parts of _scratch_options into common/xfs

["Darrick J. Wong" <djwong@kernel.org>]

From: Darrick J. Wong <djwong@kernel.org>

Move all the non-XFS code in _scratch_options into a
_scratch_xfs_options helper in common/xfs, in preparation to add ext4
bits.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
