Remove double slashes in path

* Working

[root@undercloud-0 step_1]# podman run -it --rm --net=host -v /etc/pki/tls/private/overcloud_endpoint.pem:/var/lib/kolla/config_files/src-tls/etc/pki/tls/private/overcloud_endpoint.pem undercloud-0.ctlplane.home.arpa:8787/tripleo_centos9/openstack-haproxy:latest bash
[root@undercloud-0 /]# exit

Broken (see the '//' before src-tls)
