    netfilter: Move linux/types.h inclusions outside of #ifdef __KERNEL__
    
    Greg Steuck <greg@nest.cx> points out that some of the netfilter
    headers can't be used in userspace without including linux/types.h
    first. The headers include their own linux/types.h include statements,
    these are stripped by make headers-install because they are inside
    #ifdef __KERNEL__ however. Move them out to fix this.
    
    Reported and Tested by Greg Steuck.
