SELinux: move SELINUX_MAGIC into magic.h
The selinuxfs superblock magic is used inside the IMA code, but is being defined in two places and could someday get out of sync. This patch moves the declaration into magic.h so it is only done once. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
