depends: libdmg-hfsplus: Skip CMake RPATH patching
CMake's RPATH patching apparently causes non-reproducibility in the
executables which are produced, manifesting in a difference in padding
in the .dynstr section (we found this while investigating
non-reproducibility in the "dmg" tool). This RPATH patching can be
safely skipped for executables which don't depend on internal shared
libraries.
