go.mod: update go directive to 1.18

There's no reason for this module to still be assuming the semantics
of Go 1.12. Pick 1.18 as a semi-arbitrary newer version because it's
used by a few other golang.org/x modules, and it's enough to get the
nice new features like module graph pruning, removed // +build lines,
and so on. See https://go.dev/ref/mod#go-mod-file-go.

Done with:

go get go@1.18
go mod tidy
go fix ./...

Using go1.21.1.
