Subject: watch: remove Filesys::Notify::Simple dependency

Since we already use inotify and EVFILT_VNODE (kqueue)
in -imapd, we might as well use them directly in -watch,
too.

This will allow public-inbox-watch to use PublicInbox::DS
for timers to watch newsgroups/mailboxes and have saner
signal handling in future commits.
