Kill a subprocess by sending SIGKILL to it on posix systems, or by closing the process handle on windows. If os/proc-wait already finished for proc, os/proc-kill raises an error. After sending signal to proc, if `wait` is truthy, will wait for the process to finish and return the exit code by calling os/proc-wait. Otherwise, returns `proc`. If signal is specified, send it instead. Signal keywords are named after their C count
