libsafec: wmemset_s.c scilence compilation warning

We can safely cast wchar_t * to uint32_t in this case, in order to silence the
following warning:

safeclib/wmemset_s.c: In function ‘wmemset_s’:
safeclib/wmemset_s.c:101:20: warning: pointer targets in passing argument 1 of ‘mem_prim_set32’ differ in signedness [-Wpointer-sign]
     mem_prim_set32(dest, len, value);
                    ^~~~
In file included from safeclib/wmemset_s.c:34:
safeclib/mem_primitives_lib.h:71:1: note: expected ‘uint32_t *’ {aka ‘unsigned int *’} but argument is of type ‘wchar_t *’ {aka ‘int *’}

mem_prim_set32(uint32_t *dest, uint32_t dmax, uint32_t value);
