Add intent-filter priority for CONFIGURE_VOICEMAIL intent.

The android.telephony.action.CONFIGURE_VOICEMAIL intent is only handled
by the platform, so setting an intent filter priority here will ensure
that no other app can claim to handle it.

Test: Used test app which attempts to handle the intent to verify no
intent disambiguation dialog is shown and platform handles.
