golang: Fix it to keep per-workspace bits inside go.work/

And not globally inside slapuser $HOME (which is go builtin default).

`go env` output: before:

i.e. we change $GOCACHE and $GOENV to be per-workspace:

Explanation:

- Starting from Go1.10 the go command maintains cache for built packages, test results, etc:

  https://golang.org/doc/go1.10#build

  while this cache tries to remember by which go version and in which
  environment a package was built, and reusing the cached entry only when it is
  indeed correct to do so, by keeping this cache in a shared place - not per go
  workspace - we expose it to interactions with other go installments, which,
  due to e.g. software bugs might misbehave.

  -> keeping the build cache inside go workspace makes things more safe.

- Starting from Go1.13 the go command allows to keep its configuration and environment inside a file:

  https://golang.org/doc/go1.13#go-env-w
  https://go.googlesource.com/proposal/+/master/design/30411-env.md

  The default location for such file is per-user, which can bring
  misinteraction among several go workspace installments and wrt system go
  installment.

  -> move this configuration file into inside go workspace.
