    meson: Let the linker create RPATH instead of RUNPATH tag
    
    Running meson test from the build directory in a jhbuild environment
    picks up libraries which have been installed previously because
    LD_LIBRARY_PATH takes precendence over RUNPATH. Make the linker generate
    the RPATH tag again.
