vmspawn: use poll.h rather than sys/poll.h

This does not change anything, as poll.h is a one-line wrapper of sys/poll.h.
Note that man pages e.g. poll(2) indicate to include poll.h rather than sys/poll.h.
So, let's use poll.h.

Similar to 8139906eaaced08d7924abf012561a5e8e9fbf2a.
Follow-up for 0fc45c8d20ad46ab9be0d8f29b16e606e0dd44ca.
