tests: skip tests that require blkid BLOCK_SIZE

Recent commit 84bd394cf9aaa581b4bf980f764544dda26a0305
  "writecache: use block size 4096 when no fs is found"

changed the default writecache block size from 512 to 4096
when no file system is detected.  The fs block size detection
requires the libblkid BLOCK_SIZE feature, so skip tests on
systems without this.  Otherwise, 4096 writecache added to
512 xfs leads fs io or mount failures.
