With the old method of adding build RPATHs, only the libsoup as a subproject was supported. However, it's possible to use Homebrew for libsoup too by adding libsoup as a dependency to the target (even though we don't link to it). Apple ld will not add a LC_LOAD_DYLIB entry for a library unless there are symbols that need it because meson passes `-dead_strip_dylibs`, so we can do this without issue. As a bonus, this ensures the correct build RPATHs in all cases. Additionally, we still need to explicitly add an LC_RPATH for the installed case.
