Description: Adjust path of aclchecker.py

Pagure's default_config.py file contains a hardcoded path for the
aclchecker.py script which doesn't work for us (/usr/libexec,
Fedora-specific).  This patch adjusts the path to where we actually
install the script (/usr/share/pagure).

pagure-ev/pagure_ev.service is not similarly patched because
we don't install that (we use our pagure-ev-server.service instead)
