PBAP: Add filter support for Owner contact.

Use case:
1. Add the user account which has contacts with Photos,
   Make sure owner vCard has photo added.
2. Run PTS (TC_PSE_PBB_BV_31_C & TC_PSE_PBD_BV_36_C).

Result:
User account related test cases getting failed.

Root Cause:
While retrieving vcard, filter support for owner vcard was missing.

Fix:
Filter Owner contact fields as per filter attribute request
from PBAP client before sending owner vcard.
