For now at least, I want to continue to be able run "expensive"
tests, so added this explicit test for SEEK_HOLE support.
If not available (e.g., on ext4 and tmpfs), skip it.
Otherwise, modern linux w/{btrfs,xfs,ocfs2}, run the test.

support
* tests/big-hole: Test for SEEK_HOLE support. If not available,
skip this test. Hence, this test is now skipped on linux-3.5.0 with
ext4 or tmpfs. The test runs (and passes) with at least btrfs, xfs,
or ocfs2.
