prov/util: Handle page faults in uffd monitor
In order to receive unmap events, uffd uses 'mode missing' when registering memory regions. This implies getting page fault events as well. So handle them by returning a zero-filled page. Page faults come in 3 flavors: reads, writes and writes to protected pages. The only ones we can handle are writes to non-backed pages.
