package/refpolicy: fix upstream URL in help text
The previous URL [1] currently redirects to [2], which as of this
commit is about two months old and contains a readme that just says
"PoC by Callgh0st". When the package was added with commit [3]
the help text URL matched REFPOLICY_SITE, so presumably the help was
forgotten when the site URL was updated in [4], and there has been
some kind of hostile takeover of the former upstream repository since.
