[2/3] xfs/216: always disable rmap and reflink when creating log size test fs

This test seems to check that log sizes scale up properly with the size
of the filesystem, given a carefully controlled set of mkfs parameters.
Since turning on reflink or rmap will change the minimum log size,
change the test to detect their presence and ensure they're disabled.
