Use git source

[Tõnis Tiigi]

Just a comment after looking at the code.

gockerfile/gocker2llb.go

Line 38 in 3e829bf

 Run(llb.Shlex("git clone https://" + c.Repo + ".git /go/src/" + c.Repo)). 

could use the builtin git source llb.Git() https://godoc.org/github.com/moby/buildkit/client/llb#Git instead (probably with AddMount()). The benefit of git source is that it automatically invalidates the cache when remote repo gets updated.
