    libgimp: fix the build.
    
    Autotools were not able to recognize that libgimp-@GIMP_API_VERSION@.la
    and ../libgimp/libgimp-@GIMP_API_VERSION@.la were the same dependency.
    Hence with multi-thread builds, GI scanner was not waiting for the lib
    to be totally built then failed randomly. Make the path recognizable,
    and do the same for libgimpui.
    For other libgimp*, I still need to keep a more complicated relative
    path, but since libgimp/ is the last processed folder, AFAIK it won't
    make problems.
