Fix warning in gf_serialize

Compiling under -Werror fails in gf_serialize:

crypto/ec/curve448/f_generic.c:21:27: error: argument 1 of type 'uint8_t[56]' {aka 'unsigned char[56]'} with mismatched bound [-Werror=array-parameter=]
   21 | void gf_serialize(uint8_t serial[SER_BYTES], const gf x, int with_hibit)
      |                   ~~~~~~~~^~~~~~~~~~~~~~~~~
In file included from crypto/ec/curve448/f_generic.c:12:
crypto/ec/curve448/field.h:65:28: note: previously declared as 'uint8_t *' {aka 'unsigned char *'}
void gf_serialize(uint8_t *serial, const gf x, int with_highbit);
                  ~~~~~~~~~^~~~~~
Changed parameter to pointer to fix this warning.
