selinux: use kernel linux/socket.h for genheaders and mdp

When compiling genheaders and mdp from a newer host kernel, the
following error happens:

    In file included from scripts/selinux/genheaders/genheaders.c:18:
    ./security/selinux/include/classmap.h:238:2: error: #error New
    address family defined, please update secclass_map.  #error New
    address family defined, please update secclass_map.  ^~~~~
    make[3]: *** [scripts/Makefile.host:107:
    scripts/selinux/genheaders/genheaders] Error 1 make[2]: ***
    [scripts/Makefile.build:599: scripts/selinux/genheaders] Error 2
    make[1]: *** [scripts/Makefile.build:599: scripts/selinux] Error 2
    make[1]: *** Waiting for unfinished jobs....

Instead of relying on the host definition, include linux/socket.h in
classmap.h to have PF_MAX.
