bindings: Add mctp_*_init_pollfd() API
The new API allows the binding to own the poll(2) parameters, providing
the opportunity for it to properly idle when it's unable to send control
messages. Despite this, we hold off on adjusting the behaviour directly
in this commit, as it would constitute a regression until
mctp-demux-daemon has also been converted to exploit the new API.
