Disable HAProxy apparmor profile if present

openSUSE ships a HAProxy profile which prevents the creation of the
/run/haproxy.stat file.

profile="/usr/sbin/haproxy" name="/run/haproxy.stat.21697.tmp" pid=21697 comm="haproxy" requested_mask="c" denied_mask="c" fsuid=0 ouid=0

As such, lets follow the common pattern across OSA roles to disable the
profile instead of trying to manage it.
