shell: Really take system into account in the cache key.
Fixes <https://issues.guix.gnu.org/63230>.

Previously, when running "guix shell -s X ...", OPTS would contain
something like '((system . "X") ... (system . "DEFAULT")).  Thus, since
'profile-cached-gc-root' would iterate over it in this order, "DEFAULT"
would be passed to 'profile-file-cache-key' and 'profile-spec-cache-key'
instead of "X".

* guix/scripts/shell.scm (profile-cached-gc-root): Reverse OPTS before
entering 'loop'.
