roken: Add rk_mkdir()

The Windows version of mkdir() does not share the same signature
as the POSIX version.  Add rk_mkdir() with an POSIX compliant signature
to libroken.  The current implementation ignores the 'mode' parameter
on Windows but a future implementation could provide the required
functionality with native Win32 APIs.
