[wince] We don't need cairo_win32_tmpfile on Windows CE

_cairo_win32_tmpfile() uses _open_osfhandle() which is not available
on Windows CE. However, Windows CE doesn't have the permisions problems
that necessitated _cairo_win32_tmpfile() in the first place so we can just
use tmpfile() on Windows CE.
