[PATCH] Conditionalize use of symlink() function in test suite

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

On Win32 symlink() is not available, so virstoragetest.c
must be conditionalized to avoid compile failures.

Signed-off-by: Daniel P. Berrange <berrange@xxxxxxxxxx>

Pushed as a win32 build breaker fix
