net-irc/ergo: update EAPI 7 -> 8; init script fixes

- Mostly init script fixes:
-- Add logging to init script
-- Add delay so OpenRC realises if we crashed quickly b/c of e.g. bad config
   file
-- General cleanups (like supporting multiple instances, style changes)

- Enable tests (yay! the needed files are included in tarballs now)
- Drop obsolete BDEPEND (go-module lower bound is higher)
- Drop obsolete src_compile arg to go (default in min Go in eclass)
- EAPI 8

Bug: https://github.com/ergochat/ergo/issues/1914
