Fix URL_TELEPHONY_USING_SUBID return incorrect subid's APN

URL_TELEPHONY_USING_SUBID only return the result that queried by
mcc/mnc. If there are two different carrier have same mcc/mnc,
TelephonyProvider will return all of APN to user.

Fix:
1. Return the result that queried by mcc/mnc and mvmo.
2. Add clearCallingIdentity() to prevent third party app can't query by
this URL.

Bug: 161394004
Test: By manual and atest
1. Insert an APN that MCC/MNC same as current sim
2. Query by URL_TELEPHONY_USING_SUBID and check the result
