Update API docs for android.permission.WRITE_CALL_LOG.

The API docs were incorrect in stating that WRITE_CALL_LOG does not
allow the app to READ the call log.  Contact providers have a read and
write permission and per the docs in a contact provider, the write
permission implicitly gives READ access to an app.

Fixes: 254851589
Test: Docs only change.
