For consistency, ". ./common/reflink" looks better.

This seems not necessary, cp is not used and xfs_io reflink command is
checked in _require_test_reflink.

Otherwise looks good to me. I can fix them at commit time.

Yeah - the first version used cp, but I changed it later so this an be
safely dropped.
