Should we move this function into OpamPackageVar ?

This PR doesn't seem to fix an issue that arise for packages that uses opam config var when during compilation. For instance:

#=== ERROR while compiling ocaml-freestanding.0.6.0 ===========================#
# context     2.1.0~alpha | linux/x86_64 | ocaml-variants.4.11.0+trunk | pinned(https://github.com/mirage/ocaml-freestanding/archive/v0.6.0.tar.gz)
# path        ~/.opam/4.11/.opam-switch/build/ocaml-freestanding.0.6.0
# command     ~/.opam/opam-init/hooks/sandbox.sh build make
# exit-code   2
# env-file    ~/.opam/log/ocaml-freestanding-3440035-e7966f.env
# output-file ~/.opam/log/ocaml-freestanding-3440035-e7966f.out
### output ###
# ./configure.sh
# Fatal error:
# opam: "open" failed on /home/kit_ty_kate/.opam/log/log-3441455-4438d8.out: Read-only file system

the configure script uses opam config var prefix and thus fails when this command tries to create a log file

@kit-ty-kate are you in the case of #4188?

That seems to be the case (.opam directory upgraded from opam 2.0.7)

This restriction is only for opam var affectations, should we set switch scope by default ?
