owfs: update to the latest version (v3.2p2)

Changes:
Makefile now downloads files from Github instead of SourceForge.
Changed URL, because they decided to leave SourceForge and use Github.
Added dependency libavahi-client, otherwise it doesn't build.
Dropped unnecessary patches, because both were upstreamed.
