fanotify filesystem mark tests

Hi Cyril,

This series adds some new tests to fanotify and is also available on my github tree [1].

Patches 1-2 re-structure tests fanotify{01,03} to iterate over the fanotify mark types and add some missing test coverage for FAN_MARK_MOUNT.

Patches 3-5 add test coverage for the new FAN_MARK_FILESYSTEM API, that was merged for kernel v4.20-rc1, to tests fanotify{01,03,10}. Older kernels will report TCONF on the new test cases.

Previous patches from me pending your review:
- Add test case to fanotify09 to track a bug fix in linux-next [2]
- Enhance readahead02 to track an overlayfs regression fix in v4.19 [3]

Thanks,
Amir.
