libmusicbrainz: add dependency on neon-native

* we're building separate native binary make-c-interface which is also checking
  for neon with pkg-config, when it fails it's not fatal and configure continues
  to configure target version (which finds neon correctly) but failed native
  make-c-interface build resultsin this error:
