Fix QTemporaryFile regressions and new found issues

With this change, the file template is always processed in original
QString format. Trying to generate native paths before adding a missing
placeholder mask could change the meaning of templates, such as "." and
"..", which are now tested to mean "..XXXXXX" and "...XXXXXX",
respectively.

After ensuring the template includes a placeholder mask, the path is
converted to a native *absolute* file path and the mask is sought for
again. On Windows, native paths were already absolute. On Symbian, we'd
need at least a clean path, as "." and ",," are not natively understood.

There is a requirement that the placeholder mask /XXXXXX+/ makes it
through this conversion unaltered, which relaxes prior requirements on
*nix platforms. On Windows and Symbian the conversion is under Qt's
control and not user-configurable.
