check: try to insulate the test framework from oom killer

Some of the tests in xfstests (e.g. generic/224 with 512M of memory)
consume a lot of memory, and when this happens the OOM killer will
run around stomping on processes.  Sometimes it kills the ./check
process before it kills the actual test, which means that the test
run doesn't complete.

Therefore, make the ./check process OOM-proof while bumping up the
attractiveness of the test itself, in the hopes that even if the
test OOMs we'll still be able to continue on our way.
