bug#51466: [PATCH 0/1] environment: properly parse environment variables during --check

[Kevin Boulain <kevinboulain@gmail.com>]

The PS1=; for i in 1 2 3; do echo GUIX_FLUSH_$i; done; hack appears to work
for me but here is my alternate version. I don't think we have to hack our way
around the shell if we can dump the environment variables somewhere else.

I added a test but the potato machine I'm running that on is taking a very
long time to run the whole thing (I did run the test in isolation with and
without my patch), would you mind checking it works for you (and can we use
Bash there?).

Note I'm still not sure why we have env || /usr/bin/env (in case we mess with
the PATH I guess?) so I've kept it.

Comments welcome, I haven't coded much in Guile/Scheme.
