dep/animone: make bsd.cc and x11.cc actually work
apparently I broke these, and even now the x11 code *still* doesn't want
to work correctly (at least on FreeBSD). half of the PID response codes
are just 0 or the PID for the X server itself... wtf?
maybe dwm just doesn't support the XRes extension, or I'm just stupid.
i don't know.
