bitbake: cooker: further limit inotify watches

Unfortunately we were acting on inotify notifications about any files
changing within the watched directories, not just the ones we actually
care about. In OE the build directory is in BBPATH and hence it gets
watched, and we write things like bitbake.lock and
bitbake-cookerdaemon.log to that directory, hence effectively
notifications were being tripped on every bitbake invocation. To avoid
this, record which file/subdirectory we're interested in against each
watched directory so we can ignore any events for files/subdirectories
we don't care about.

Additionally, if we move up to the parent dir, ensure we haven't already
seen it before adding a watch on it (we were previously calling
watcher.add_watch() on the same directory multiple times before in a
typical OE configuration).
