describe: Save the original value of (program-arguments).
Fixes <https://bugs.gnu.org/42688>.
Reported by pkill9 <pkill9@runbox.com>.
This ensures that 'guix repl -s SCRIPT' give SCRIPT the right value
of (current-profile), which in turn ensures that (%package-module-path)
is initialized with the right set of channels.
* guix/describe.scm (initial-program-arguments): New variable.
(current-profile): Use it.
* guix/scripts/repl.scm (guix-repl): Call 'current-profile' before
'set-program-arguments'.
