fstests: detect btrfs compression and disable certain tests

Our nightly xfstests runs exposed a set of tests that always fail if we
have compression enabled.  This is because compression obviously messes
with the amount of data space allocated on disk, and these tests are
testing either that quota is doing the correct thing, or that we're able
to completely fill the file system.

Add a helper to check to see if we have any of our compression related
mount options set and simply _not_run for these specific tests.
