fswatcher: fix bsd support

Fix the following error when running maildir on freebsd:

 could not create file system watcher: Unsupported OS: freebsd

Do not register based on os type. Register based on supported API.
Rename linux -> inotify and darwin -> fsevents. Only build fsevents on
darwin, and inotify on all other platforms.
