multimedia/livego: update 0.0.15 -> 0.0.20 and take maintainership

Changelog: https://github.com/gwuhaolin/livego/releases/tag/0.0.20

Major changes:

• Fix Memory leak
• Update ignore rules
• Add RTMPS support
• added hls via https support

Port changes:

go-redis package don't fit GH_TUPLE expectations by creating the wrong
directory structure (create a ${WRKDIR}/go-redis directory where
${WRKDIR}/redis is expected) leading to post-extract move errors, so it
must be handled separately.
