    meson: fix pkg-config generation with internal dependencies
    
    When building with internal dependencies (subprojects) meson fails to
    configure the build with the following message:
    
    subprojects/atk/atk/meson.build:161:10: ERROR: requires argument not a string, library with 
pkgconfig-generated file or pkgconfig-dependency object, got <InternalDependency null: True>
    
    Use libraries instead of requires when calling pkgconfig.generate() to
    make the configuration succeed.
