Test lib/io_xs fails for perl 5.6.1 on NT

The test lib/io_xs comes through on my NT box only when I run it
as administrator. Using a filemonitor I would guess that this is
because IO​::File​::new_tmpfile tries to create a temporary file in
the root directory c​:\, which is write-accessible for
administrators only on my system.

Maybe IO​::File​::new_tmpfile should evaluate some environment
variable to get a path to a directory which is intended for
temporary files, and, in particular, guaranteed to be
world-writable.

I've tested perl 5.8.8/MSVC and 5.14.0/gcc, with C​:\ blocked for file
creation. It works. Perl uses tmpfile() from Windows, so it is possible
that it was fixed after NT 4.0.

P.S. Program for test attached.
