Darrick J. Wong 813524b566 tests: use lowercase variables for all the new reflink tests
Since $TESTDIR is a local variable, make it lowercase to avoid
confusion with $TEST_DIR.  While we're at it, make all the local
variables lowercase.

# FS QA Test No. 205
#
# See what happens if we CoW blocks 2-4 of a page's worth of blocks when the
# second block is a regular block.
#
# This test is dependent on the system page size, so we cannot use md5 in
# the golden output; we can only compare to a check file.
