Improve signal name<->number conversions.
Include all the signals, not just the POSIX ones. In particular, improve support for real-time signals. My attempt to switch AOSP builds over to toybox timeout got reverted when I broke the ART build bots which use SIGRTMIN+2. Also fix `kill -l 3` to show "QUIT" and `kill -l QUIT` to show "3". Also make the `kill -l` output include numbers and names, and format it to look better on a 80x24 tty, because it's always August 1978 somewhere.
