[LTP] Split some fanotify tests

[Petr Vorel]

Hi Amir,

FYI we were thinking with Martin about splitting some of the fanotify tests.
Why?

Some of the fanotify tests are hard to review (e.g. fanotify{10,13,14}.c,),
because the have a lot of results.

Also other problem is that some enterprise kernels does not backport minor fixes
and the usual approach is to whitelist the issue based on exit code. But this
cannot be done on the test which has many results. We could workaround it with
tst_kvercmp2(), but that's kind of a last result.

Kind regards,
Petr
