    installed-tests: Fix building libgjstesttools
    
    ...on Visual Studio-style builds, since we need to explicitly mark the
    prototypes in the header for export, otherwise the build will fail as
    running g-ir-scanner will fail to find the export library for the DLL
    that was built.
    
    (cherry-picked from commit commit 76b092c1)
