*: staticcheck linting cleanup

[mreiferson]

These seem like mostly good things, should probably run this as part of tests too?

looks like i386 test is kinda broken, also go-1.17 staticcheck

[mreiferson]

OK, this should be ready to go now @ploxiln

LGTM 👍

to summarize what I observed:

• remove old go-bindata for go < 1.16
• remove ssl3.0 add tls1.3
• remove tlsConfig.BuildNameToCertificate() call, deprecated, "NameToCertificate" not needed anymore
• fix ticker goroutine leak in lookupLoop() ?
• remove logging from QueryAnyAuthd(), return one big error which is eventually logged in protocol_v2.go
• remove bits of dead code
• mechanical cleanups with no functional change (ioutil renames, type switch cleanup ...)

All good stuff 💯
