Normalize the exceptions.

qemu-ga's socket activation support was not obeying the LISTEN_PID
environment variable, which avoids that a process uses a socket-activation
file descriptor meant for its parent.
Mess can for example ensue if a process forks a children before consuming
the socket-activation file descriptor and therefore setting O_CLOEXEC
on it.
Luckily, qemu-nbd also got socket activation code, and its copy does
support LISTEN_PID. Some extra fixups are needed to ensure that the
code can be used for both, but that's what this patch does. The
main change is to replace get_listen_fds's "consume" argument with
the FIRST_SOCKET_ACTIVATION_FD macro from the qemu-nbd code.
