wildmatch test: mark test as EXPENSIVE_ON_WINDOWS

Mark the newly added test which creates test files on-disk as
EXPENSIVE_ON_WINDOWS. According to [1] it takes almost ten minutes to
run this test file on Windows after this recent change, but just a few
seconds on Linux as noted in my [2].

This could be done faster by exiting earlier, however by using this
pattern we'll emit "skip" lines for each skipped test, making it clear
we're not running a lot of them in the TAP output, at the cost of some
overhead.
