environment: Fix ‘--check’ with exported PS1 variable.

If your .bashrc (unnecessarily) exports PS1 and you’re in a non-login
shell, Guix crashes:

user@popigai:~$ guix shell --check coreutils
guix shell: checking the environment variables visible from shell '/bin/bash'...

user@popigai:~$

This is because the match pattern doesn’t expect `(vhash-assoc "PS1" actual)`
to return a pair.

* guix/scripts/environment.scm (validate-child-shell-environment): Change
match pattern to expect a pair.
