xfstests: filter new repair/mkfs output for CRCs

This patch it to ensure that xfstests passes on non-crc filesystems
with a CRC enabled userspace.

Filter out the mkfs/xfs_info CRC line from tests that capture the
output of these commands.

Filter out new error noise from xfs_repair that occurs for
xfs_repair as a result of the CRC changes.
