aqbanking: fix cross, change prefix detection for the cmake config file

The cmake configuration file for aqbankung always uses /usr as prefix
which causes issues while cross-compiling. This adds a patch to change
the detection to do it the same way most KDE/QT software does it.

Closes: #10663 [via git-merge-pr]
