Unlike ‘rm -rf ~/.cache/guix/substitute’ this respects XDG_CACHE_HOME.

Use the --OPTION form for consistency with the existing ‘guix substitute’
interface, where other guix subcommands would prefer an ACTION.  This
subcommand really supports only one OPTION at a time, anyway.

* guix/scripts/substitute.scm (guix-substitute):
Add a new ‘--clear-cache’ option argument.
(show-help): Document it.
