fanotify: Fix sys_fanotify_mark() on native x86-32
commit 2ca408d9c749c32288bc28725f9f12ba30299e8f upstream.
Commit
121b32a58a3a ("x86/entry/32: Use IA32-specific wrappers for syscalls taking 64-bit arguments")
converted native x86-32 which take 64-bit arguments to use the
compat handlers to allow conversion to passing args via pt_regs.
sys_fanotify_mark() was however missed, as it has a general compat
handler. Add a config option that will use the syscall wrapper that
takes the split args for native 32-bit.
[ bp: Fix typo in Kconfig help text. ]
