Enhanced permission checks for TelephonyManager#endCall() API.

The existing permission checks require CALL permission in order to end
an ongoing call or reject an incoming call.  The Telecom equivalent of
this API requires MODIFY_PHONE_STATE.  Since this API IS in fact a system
API, modifying the permission requirements to require the same
MODIFY_PHONE_STATE permission.

Test: Manual testing per bug reproduction steps.
