libsepol: initialize s in constraint_expr_eval_reason

clang's static analyzer reports that s[0] can be uninitialized when used
in:

    sprintf(tmp_buf, "%s %s\n",
                    xcontext ? "Validatetrans" : "Constraint",
                    s[0] ? "GRANTED" : "DENIED");

Silence this false-positive issue by making s always initialized.
