signal: clean up kernel-doc comments

Fix kernel-doc warnings in kernel/signal.c:

kernel/signal.c:1830: warning: Function parameter or member 'force_coredump' not described in 'force_sig_seccomp'
kernel/signal.c:2873: warning: missing initial short description on line:
 * signal_delivered -

Also add a closing parenthesis to the comments in signal_delivered().
