[OE-core] [PATCH] kernel-devsrc: add selinux include files needed by scripts/selinux build

[Victor Kamensky]

If CONFIG_SECURITY_SELINUX=y is enabled in kernel configuration, then
'make scripts' command in /usr/src/kernel fails to build
utilities under scripts/selinux that would be pulled in by this config:

  HOSTCC  scripts/selinux/genheaders/genheaders
scripts/selinux/genheaders/genheaders.c:19:10: fatal error: classmap.h: No such file or directory
 #include "classmap.h"

To address this issue add security/selinux/include files into
kernel-devsrc.

To reproduce this issue add to conf/local.conf selinux fragment:
KERNEL_EXTRA_FEATURES_append = " cgl/features/selinux/selinux.scc"
build core-image-lsb-sdk and run 'cd /usr/src/kernel; make scripts'
