util: Rename and make global vu_remove_watch()

vu_remove_watch() is used in vhost_user.c to remove an fd from the global
epoll set.  There's nothing really vhost user specific about it though,
so rename, move to util.c and use it in a bunch of places outside
vhost_user.c where it makes things marginally more readable.
