bug#52984: gimagereader: build failure: undefined references

[Christopher Howard]

gimagereader fails to build, giving a lot of undefined reference errors during 
building of qt sources. E.g.:

```
ld: CMakeFiles/gimagereader.dir/qt/src/scanner/ScannerSane.cc.o: in function 
`ScannerSane::doCompletePage()':
/tmp/guix-build-gimagereader-3.3.1.drv-0/gimagereader-3.3.1/qt/src/scanner/ScannerSane.cc:521:
 undefined reference to `Scanner::pageAvailable(QString const&)'
ld: CMakeFiles/gimagereader.dir/qt/src/scanner/ScannerSane.cc.o: in function 
`ScannerSane::run()':
/tmp/guix-build-gimagereader-3.3.1.drv-0/gimagereader-3.3.1/qt/src/scanner/ScannerSane.cc:66:
 undefined reference to `Scanner::initFailed()'
ld: CMakeFiles/gimagereader.dir/qt/src/scanner/ScannerSane.cc.o: in function 
`ScannerSane::setState(Scanner::State)':
/tmp/guix-build-gimagereader-3.3.1.drv-0/gimagereader-3.3.1/qt/src/scanner/ScannerSane.cc:117:
 undefined reference to `Scanner::scanStateChanged(Scanner::State)'
ld: CMakeFiles/gimagereader.dir/qt/src/scanner/ScannerSane.cc.o: in function 
`ScannerSane::failScan(QString const&)':
/tmp/guix-build-gimagereader-3.3.1.drv-0/gimagereader-3.3.1/qt/src/scanner/ScannerSane.cc:122:
 undefined reference to `Scanner::scanFailed(QString const&)'
collect2: error: ld returned 1 exit status
```
