fixup TP/Flash blocklist URL prefs

See comment https://github.com/ghacksuserjs/ghacks-user.js/issues/103#issuecomment-300911966 - `*safebrowsing.provider.mozilla.*` is for Flash & TP ONLY (original article by francois had a *slight!!* error since fixed)

This means that 0410d was not shared by TP and SB and to clear it all up .. 0410d is moved to 0420's. 0420's also gets the flash pref 0440 moved into the 0420's.

Now it's all tidy: 0410's = google and SB, 0420's = mozilla & TP+Flash
