checkpolicy: delay down-cast to avoid align warning

Browse source 
Delay the down-cast from hashtab_datum_t, alias void*, to the actual
type once its kind has been determined.

    module_compiler.c:174:19: warning: cast from 'symtab_datum_t *' (aka 'struct symtab_datum *') to 'level_datum_t *' (aka 'struct level_datum *') increases required alignment from 4 to 8 [-Wcast-align]
                            *dest_value = ((level_datum_t *)s)->level->sens;
                                           ^~~~~~~~~~~~~~~~~~
