ipa-advise: update url of cacerdir_rehash tool
On legacy systems which don't have cacerdir_rehash tool (provided by authconfig)
the generated advise script downloads this tool from project page and uses it.
After decommision of Fedorahosted and move of authconfig project to Pagure,
this url was not updated in FreeIPA project.
This patch updates the url.
