e6fbd1759c selftests: complete kselftest include centralization 
This follow-up patch completes centralization of kselftest.h and
ksefltest_harness.h includes in remaining seltests files, replacing all
relative paths with a non-relative paths using shared -I include path in
lib.mk

Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on
riscv, arm64, x86_64 and powerpc arch.

e51bd0e595 selftests/fs/mount-notify: Fix compilation failure. 
Commit c6d9775c20 ("selftests/fs/mount-notify: build with tools include
dir") introduces the struct __kernel_fsid_t to decouple dependency with
headers_install.  The commit forgets to define a macro for __kernel_fsid_t
and it will cause type re-definition issue.

781091f3f5 selftests/fs/mount-notify: add a test variant running inside userns 
unshare userns in addition to mntns and verify that:

1. watching tmpfs mounted inside userns is allowed with any mark type
2. watching orig root with filesystem mark type is not allowed
3. watching mntns of orig userns is not allowed
4. watching mntns in userns where fanotify_init was called is allowed

mount events are only tested with the last case of mntns mark.

e897b9b133 selftests/filesystems: create get_unique_mnt_id() helper 
Add helper to utils.c and use it in mount-notify and statmount tests.

Linking with utils.c drags in a dependecy with libcap, so add it to the
Makefile of the tests.

c6d9775c20 selftests/fs/mount-notify: build with tools include dir 
Copy the fanotify uapi header files to the tools include dir
and define __kernel_fsid_t to decouple dependency with headers_install
and then remove the redundant re-definitions of fanotify macros.
