local monitors: make more idiomatic use of GObject

Browse Source 
Stop abusing constructor() to do startup work, adding _start() calls
instead.

The backends themselves still use constructor() although a patch will be
following to also fix inotify.

The reason for using a separate start() call instead of constructed()
will become apparent in future commits.
