Mark this test as unsupported on Windows systems

There is a strange issue happening with command line processing though. The
command line argument
   --export-dynamic-symbol 'f*'
does not have the single quotes stripped on some Windows targets (but not
all). This causes the glob matching to fail, which means the test fails on
some Windows bots and passes on others.

This is expected to be a temporary measure to get bots back to green. I've not
found a commit that has caused a behavioral change that could be reverted
instead, so this could be an issue with lit or test machine configuration.

 ## For an executable, --export-dynamic-symbol exports a symbol if it is non-local and defined.
