[PATCH] Fix SELinux build for "make O=..."

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch fixes the SELinux build for "make O=..." by removing the use of
-include and eliminating the global.h file, adding appropriate individual
#include's to the various files in the security/selinux/ss subdirectory.
The compilation error was reported by Sam Ravnborg and again by Adrian
Bunk.
