Use of `replace` in go.mod breaks delve installation using `go install`. (see https://github.com/golang/go/issues/40276) Workaround this limitation by explicitly require the fork github.com/go-delve/liner. go-delve/liner@v1.2.2-1 already has go.mod module name fixed to be github.com/go-delve/liner. Fixes go-delve/delve#2904
