runtime.Version() will always give an accurate build host version

https://cs.opensource.google/go/go/+/refs/tags/go1.18.3:src/runtime/extern.go;l=251-266

For the host's GOOS and host's GOARCH they're not available so they must still be passed in via ldflags

matches the go version cli output

https://github.com/golang/go/blob/master/src/cmd/go/internal/version/version.go#L76

make fastly now uses goreleaser. I removed the cleanup comment and left the ldflags for the "dev" builds
Maybe the whole LDFLAGS entry can be removed and the dev builds just dont have version info?

No problem.

It'd be nice if runtime or buildinfo also exposed the host os and arch and we wouldn't need any of these env vars (the info is there but only within an internal library :/) but this will do for now

I just realized I didn't touch the Dockerfiles but it looks like they grab the release so that doesn't need touching

I do need to fix the snapshot tests though by the looks of it
