selinux: include sys/socket.h in host programs to have PF_MAX
Compiling with clang and -Wundef makes the compiler report a usage of
undefined PF_MAX macro in security/selinux/include/classmap.h:
In file included from scripts/selinux/mdp/mdp.c:48:
security/selinux/include/classmap.h:37:31: warning: no previous
extern declaration for non-static variable 'secclass_map'
[-Wmissing-variable-declarations]
struct security_class_mapping secclass_map[] = {
^
security/selinux/include/classmap.h:235:5: error: 'PF_MAX' is not
defined, evaluates to 0 [-Werror,-Wundef]
#if PF_MAX > 43
^

struct security_class_mapping secclass_map[] = {

PF_MAX is defined in include/linux/socket.h but not in
include/uapi/linux/socket.h. Therefore host programs have to rely on the
definition from libc's /usr/include/bits/socket.h, included by
<sys/socket.h>.
Fix the issue by using sys/socket.h in mdp and genheaders. When
classmap.h is included by security/selinux/avc.c, it uses the kernel
definition of PF_MAX, which makes the test consistent.
