Subject: home: services: shells: Double-quote environment variable values.

Fixes <https://issues.guix.gnu.org/56540>.

Until now, environment variable values were emitted unquoted, producing
invalid shell code if the value contains spaces for example.

* gnu/home/services/shells.scm (serialize-posix-env-vars): Define
'shell-quote' procedure in staged code and use it for #$value.
* tests/guix-home.sh: Add test for PS1 variable with a value containing
spaces.
