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.
