qt: Add pattern used for WKD lookup to result

* lang/qt/src/qgpgmewkdlookupjob.cpp (run_wkd_get): Change type of
arg email.
(lookup_keys): Add pattern to result.
* lang/qt/src/wkdlookupresult.h (class WKDLookupResult): Add arg
pattern to c'tors. Add member function pattern.
* lang/qt/src/wkdlookupresult.cpp (class WKDLookupResult::Private):
Add field pattern.
(WKDLookupResult::WKDLookupResult): Pass pattern to pimpl.
(WKDLookupResult::pattern): New.

* lang/qt/tests/t-wkdlookup.cpp (testWKDLookupAsync, testWKDLookupSync,
testLookupWithNoResultAsync): Check pattern.
