Revert "cmd/go: use shallow clones for new git checkouts"

This reverts commit bc1f9d20b40998b87c9a5f56f2b22595de65c2d4.

The current go-get strategy doesn't support cases that servers
cannot handle shallow clients.

Also, `go get -u` is broken and is not compatible with already
go-getted unshallow repos.

Fixes #13213.
Fixes #13206.
