environment: '-C' creates namespaces where the user is not root.
* guix/scripts/environment.scm (launch-environment/container): Add UID and GID. Use them in PASSWD and GROUPS. Pass them as #:guest-uid and #:guest-gid to 'call-with-container'. * tests/guix-environment-container.sh: Test the inner UID. In '--user' test, replace hard-coded 0 with 1000. * doc/guix.texi (Invoking guix environment): Adjust accordingly.
