configure, meson: allow enabling vhost-user on all POSIX systems

With the possibility of using a pipe pair via qemu_pipe() as a
replacement on operating systems that doesn't support eventfd,
vhost-user can also work on all POSIX systems.

This change allows enabling vhost-user on all non-Windows platforms
and makes libvhost_user (which still depends on eventfd) a linux-only
feature.
