[LTP] [PATCH] syscalls/fanotify26: Move from staging to syscalls

[Edvard Conrad]

The kernel fix the second test case needs, commit c3d355f427ce ("fs:
let backing files inherit FMODE_NONOTIFY from the user file"), was
merged into Linus' tree on 2026-10-30 and will appear in v7.4-rc1.

Move the test out of runtest/staging, and record the fix in a
linux-git tag so that a failure points at the missing kernel commit
rather than at the test.

The follow-up Petr asked for on the fanotify26 thread:
  https://lore.kernel.org/ltp/20261030110233.GA66190@pevik/

The fix is in Linus' tree as of 2026-10-30, but v7.4-rc1 is not tagged
yet, so if you would rather hold this until the rc is out, please do.

Kernel commit:
  https://git.kernel.org/torvalds/c/c3d355f427cea70fbe31b49e21f1915dbf37f2e6

Both test cases pass on a kernel carrying the fix, and the second one
fails without it; that is unchanged by this patch, which only moves the
runtest entry and adds the tag.
