xmlsecurity PDF sign: enable unit tests on Windows

Now that the mscrypto part of PDFDocument::ValidateSignature() is
implemented it's possible to run these tests on Windows as well,
provided the machine has at least one signing certificate installed.

Also fix a race, where the workdir of the signing test was used by the
pdfsigning test.
