meson: Don't attempt to use version scripts on macOS

Browse Source 
macOS libraries don't support symbol versioning, so the only
result that we achieve by passing additional flags to the linker
is a bunch of messages like

  ld: warning: ignoring file .../libvirt/build/src/libvirt.syms,
  building for macOS-x86_64 but attempting to link with file built
  for unknown-unsupported file format ( 0x23 0x20 0x57 0x41 ... )

being produced during the build.
