s390: avoid peeking eof after __vector

Same like PR101168, it is need for s390 to
avoid peeking eof after vector keyword.
And similar test case is also ok for s390.

Test with cross-compiling, this code can fix the issue as expected.

The powerpc issue was fixed in GCC 13 (most likely by
r13-220-g067fe66c8ba9b16feacf66fce9ae668091e42821 ).

s390 most likely needs the same treatment:
```
[apinski@xeond2 rs6000]$ git diff ../s390/s390-c.cc
diff --git a/gcc/config/s390/s390-c.cc b/gcc/config/s390/s390-c.cc
index 8d3d1a467a8..8096b1ff7c1 100644
--- a/gcc/config/s390/s390-c.cc
+++ b/gcc/config/s390/s390-c.cc
@@ -275,7 +275,7 @@ s390_macro_to_expand (cpp_reader *pfile, const cpp_token
*tok)
   /* __vector long __bool a; */
   if (ident == C_CPP_HASHNODE (__bool_keyword))
expand_bool_p = true;
-  else
+  else if (ident)
{
  /* Triggered with: __vector long long __bool a; */
  do

```

I cannot test this at all, and a similar testcase in PR 101168 should be added
for s390.
