GHA/windows: skip flaky test 498

On suspect of strain on the runtime env/pipes, disable this test, which
is flaky due to `runtests` detecting a 2009 result code from curl, while
curl is returning the expected 56:

```
test 0498...[Reject too large HTTP response headers on endless redirects]

curl returned 2009, when expecting 56
 498: exit FAILED
== Contents of files in the log/5/ dir after test 498
[...]
   0     0    0     0    0     0      0      0 --:--:--  0:00:10 --:--:--     0
 curl: (56) Too large response headers: 6144086 > 6144000
```

In such cases the number of log lines for this single test is 4800. In
comparison the total number of log lines for a clear test run is 3800.

Seen with mingw, dl-mingw, msvc CI jobs.
