mash: Makes mash and service:ui not establish outgoing connections

The ui service was connecting to chrome for the ime driver. As the ui
service is a singleton and chrome isn't, this triggered launching
another process of chrome, which we don't want. Turns out having ui
connect to chrome for the ime driver is unnecessary as chrome already
does this. So, removing the code.

Mash was connecting to the chrome for the keyboard service. This is
also problematic for similar reasons, so removing it too. Filed bug
to have chrome register keyboard with mash.
