selinux: ensure av_permissions.h is built when needed

[ Upstream commit 4ce1f694eb5d8ca607fed8542d32a33b4f1217a5 ]

The Makefile rule responsible for building flask.h and
av_permissions.h only lists flask.h as a target which means that
av_permissions.h is only generated when flask.h needs to be
generated.  This patch fixes this by adding av_permissions.h as a
target to the rule.
