qt: Support reading signed/encrypted archives directly from a file

* lang/qt/src/decryptverifyarchivejob.cpp,
lang/qt/src/decryptverifyarchivejob.h (DecryptVerifyArchiveJob): Add
member functions setInputFile, inputFile.
* lang/qt/src/decryptverifyarchivejob_p.h
(DecryptVerifyArchiveJobPrivate): Add member m_inputFilePath.
* lang/qt/src/qgpgmedecryptverifyarchivejob.cpp (decrypt_verify): Move
creation of indata to decrypt_verify_from_io_device.
(decrypt_verify_from_io_device, decrypt_verify_from_file_name): New.
(QGpgMEDecryptVerifyArchiveJob::start): Use
decrypt_verify_from_io_device instead of decrypt_verify.
(QGpgMEDecryptVerifyArchiveJobPrivate::startIt): Start the job with the
values from member variables.

* lang/qt/tests/run-decryptverifyarchivejob.cpp (createInput): Remove.
(main): Remove creation of input. Make the job read the archive directly
from the given archive name.

This makes it possible to tell gpgtar to read the signed/encrypted
archive directly from a specified file bypassing GpgME's Data IO.
