Start paving the way for vold calls over Binder.

This change is the bare minimum needed to publish a new vold
Binder service and move the simple "reset" call over to go through
the new interface.

The new rules here are mirrored on the existing installd rules, but
with a handful of neverallow rules relaxed due to funky interactions
with hal_client_domain().

Test: builds, boots
