Tests the noatime, relatime, strictatime and nodiratime mount options.
There is an extra check for Btrfs to ensure that the access time is
never updated on read-only subvolumes. (Regression test for bug fixed
with commit 93fd63c2f001ca6797c6b15b696a484b165b4800)

v1->v2:
- Fix typo in _cleanup()
- Explicitly passing relatime mount option
- Adding _require_relatime method to common/rc
- Adding extra test for read-only mounts
