[rhythmbox/wip/sam/meson: 37/39] Fix binary install locations, and set rpath when installing

[Sam Thursfield <sthursfield src gnome org>]

commit 357a5e6cb84929449fd68b4549adc29773f8fe34

    Fix binary install locations, and set rpath when installing
    
    The rpath is needed if we install to a non-standard prefix to avoid
    having to manually set LD_LIBRARY_PATH.
