Add more URI patterns for accessing TV metadata

The following URI patterns are added:
  content://com.android.tv/input/*/*/channel
  content://com.android.tv/input/*/*/channel?browsable_only=
  content://com.android.tv/channel/#/program
  content://com.android.tv/channel/#/program?start_time=&end_time=

This allows us to disable user-provided selection on query/delete/update to help
avoid SQL injection.
