hghave: disallow symlinks on Windows
Symlinks on Windows require either a special priviledge, or enabling Developer
Mode. It's probably the latter that is enabled on the new CI machine. But
since Mercurial itself is saying no to symlinks on Windows, the tests for
symlinks shouldn't be attempted. This should fix a lot of the noise in the py3
tests.
