This exposes a Linux-specific syscall for sending a signal to a process
identified by a file descriptor rather than a pid.

For simplicity, we don't support the siginfo_t parameter to the syscall. This
parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which
Python also doesn't support.
