winetest: Don't count on $TMPDIR staying set.

The BEGIN code block will be run the first time the web server loads
the CGI script. However the web server may use caching techniques that
result in the script being run a second time while skipping the BEGIN
code block. Furthermore $TMPDIR may have been unset which will cause
tempdir(DIR => "") to fail with a permission denied error.
Perl variables are preserved however so use them instead.
Still set $TMPDIR so the CGI temporary file will be on the right
filesystem, resulting in a faster move operation.
