mjansson-mdns: add new recipe

Public domain mDNS/DNS-SD library in C

Add github namespace to recipe name and handle it in CVE_PRODUCT because
there already is a different mdns recipe in meta-openembedded.

Example application is built but not installed.
This is good to verify that current toolchain is copatible with headers.
