Panic on genji version

[tdemin]

After having run go get -u -v github.com/genjidb/genji/cmd/genji, trying to run genji version results in this output:

The Git commit I built Genji from is 375ed7a.

I supposed you run go get outside of a module? When that happens debug.ReadBuildInfo returns nil, which then panics here: https://github.com/genjidb/genji/blob/375ed7aafa0f1d508d14671adb450ac6eb4789dd/cmd/genji/main.go#L100

I think we should also provide official binaries via GitHub releases. The GOPATH go get is essentially development version, so we can’t do much about it.

@tie good idea, I added an issue about that here #269
