python: Wrap 'gpgme_op_keylist_from_data_start'.

* NEWS: Update.
* lang/python/gpg/core.py (Context.keylist): New keyword argument
'source'.  If given, list keys from 'source'.
* lang/python/gpgme.i: Wrap the argument to
'gpgme_op_keylist_from_data_start'.
* lang/python/tests/Makefile.am (py_tests): Add new test.
* lang/python/tests/support.py (EphemeralContext): Do not throw an
error if no agent has been started in the context.
* lang/python/tests/t-keylist-from-data.py: New file.
