[Solution] Implement tizen privilege for W3C API.
If web application contains "http://tizen.org/privilege/geolocation"
with tizen:privilege tag, web application uses geolocation without
security warning popup. In this case, only local origin is allowed to use.

Even this information is showed in the setting menu(Advanced settings->
Exceptions settings), user cannot delete it.(This list will display
by read-only property)
