Darrick J. Wong 2616587012 reflink: fix style problems in existing tests
Fix style problems such as unnecessary use of quotes, add helper
variables to reduce visual clutter, and other minor fixes to make the
first batch of tests more closely resemble the second round tests.

# FS QA Test No. 129

# of a multi-level refcount btree, and that metadump will successfully copy
# said block.
