yajl: Import older 1.0.12 version

* it was available in openwebos/meta-oe and in
  older openembedded/meta-oe
* openembedded/meta-oe now has 2.0.4 which is not
  compatible with current components, see
  see [OW-39], [OW-46], [OWEBOS-3022]
* import 1.0.12 to meta-webos so we can use
  openembedded/meta-oe and yajl-1.0.12 until
  all components are compatible with 2.0.4
