file capabilities: allow sigcont within session
Fix http://bugzilla.kernel.org/show_bug.cgi?id=9247
Allow sigcont to be sent to a process with greater capabilities if it is in
the same session. Otherwise, a shell from which I've started a root shell
and done 'suspend' can't be restarted by the parent shell.
Also don't do file-capabilities signaling checks when uids for the
processes don't match, since the standard check_kill_permission will have
done those checks.
