mdns: move from meta-intel-iot-middleware

The following improvements have been made over the recipe that was in
meta-intel-iot-middleware (a layer which is no longer actively
maintained):

* Upgrade to latest upstream version (765.50.9)
* Fix compilation failures by passing CC and LD
* Fix "no GNU hash in the ELF binary" issue
* Point S at the correct source subdirectory so that "make clean" works
* Fix lack of soname on libdns_sd.so leading to missing RDEPENDS QA error
* Add SUMMARY
