LP:1958433 curtin workaround for xfs in centos70

The XFS implementation in CentOS 7 does not support the reflink feature,
and refuses to mount with it, leaving the system boot in emergency mode.

So, if 'mkfs.xfs' in the commissioning image (used for deployment) knows
about 'reflink=0|1', create a wrapper to use '-m reflink=0' for CentOS 7.

The commands to generate the wrapper are general, long, and unoptimized,
for better compatibility between Bionic/Focal/Jammy comissioning images.

Example with Focal:
