With current versions of mingw-w64, TLS destructors that are registered
while executing TLS destructors are lost and leaked.
The root cause does get fixed further upstream in mingw-w64 in
71eddccd74
though, but mark the test as unsupported for now. The marking can be
removed later when the version used in the CI runner has been updated
to include the fix.
