Allow managed profile to modify networks

If the current foreground user has a managed profile, apps running in that
profile should have the same permissions to add/remove/modify networks as
apps running as the foreground user itself.

This is a re-submit of
https://partner-android-review.googlesource.com/#/c/529950/
with updated unit tests that will also work after merging to N/master.
