Subject: [PATCH v1] apparmor: Remove duplicate macro list_entry_is_head()

Strangely I hadn't had noticed the existence of the list_entry_is_head() in
apparmor code when added the same one in the list.h. Luckily it's fully
identical and didn't break builds. In any case we don't need a duplicate
anymore, thus remove it from apparmor code.
