libsemanage: include internal header to use the hidden function prototypes

When functions from libsemanage calls other functions that are exported,
these functions need to be "wrapped" using hidden_proto() macro. This is
done in headers such as "user_internal.h". Several functions in
genhomedircon.c are not doing this, which makes building with -flto
fail with errors such as:

    /usr/bin/ld: /tmp/libsemanage.so.1.KebOLC.ltrans1.ltrans.o: in
    function `user_sort_func':
    /home/tkloczko/rpmbuild/BUILD/libsemanage-2.9-rc1/src/genhomedircon.c:758:

    /usr/bin/ld:

    /home/tkloczko/rpmbuild/BUILD/libsemanage-2.9-rc1/src/genhomedircon.c:905:

Include the missing headers.
