Fix GCC10 issue in guest_s390_defs.h typedef enum type s390x_vec_op_t.

GCC10 defaults to -fno-common which produces this error:

  guest_s390_defs.h:291: multiple definition of `s390x_vec_op_t

This is because GCC10 detects there are multiple definitions of the
variable s390x_vec_op_t. We don't want to define a variable though.
We had wanted to define a type (one that currently isn't used).
Fix this by making it a typedef enum.
