qt: Extend SignKeyJob to create trust signatures

* lang/qt/src/signkeyjob.h (SignKeyJob::setTrustSignature): New.
* lang/qt/src/qgpgmesignkeyjob.h, lang/qt/src/qgpgmesignkeyjob.cpp
(QGpgMESignKeyJob::setTrustSignature): New.
* lang/qt/src/qgpgmesignkeyjob.cpp (sign_key): Handle trust signatures.
(QGpgMESignKeyJob::start): Pass trust signature attributes to sign_key.
(QGpgMESignKeyJob::setTrustSignature): New.
