FIXES 37887

if you manage to patch the syscall table, then the setpag() in the
patched setgroups syscall and creates a new session keyring. it does
contain the right pag id but this isnt the intended behavior.

so setpag() becomes __setpag() which just does the group insertion.
(and perhaps it should be called something else?). the stat count for
the setpag operation might be more correct now (instead of also counting
the pag restores).
