qt: Allow specifying import options when importing keys

* lang/qt/src/importjob.cpp, lang/qt/src/importjob.h (class ImportJob):
Add member functions setImportOptions and importOptions.
* lang/qt/src/importjob_p.h (struct ImportJobPrivate): Add member
m_importOptions.
* lang/qt/src/qgpgmeimportjob.cpp (import_qba): Add arg importOptions
and adjust the callers. Set import options context flag.

* lang/qt/tests/t-import.cpp (ImportTest): Add member function
testImportWithImportOptions.
