Documentation/sysctl: coredump: add %F for pidfd number

Browse Source 
In commit b5325b2a27 ("coredump: hand a pidfd to the usermode coredump
helper") a new core_pattern specifier, %F, was added to provide a pidfs
to the usermode helper process referring to the crashed process.

Update the documentation to include the new core_pattern specifier.
