QTemporaryFile: More dead code elimination

There are exactly 2 uses of the _gettemp function: one for windows
platforms, one for all others. Windows requests a file name, others
request a valid file descriptor for that file name.

Despite the 2 distinct use cases, the code was full of #ifdefs to keep
never used code paths compiling.

With this change the qt_mkstemp wrapper is eliminated, together with
dead code inside if (doopen) {} blocks on Windows platforms. The more
proper Q_OS_WIN macro is preferred to Q_WS_WIN.

_gettemp is also changed to return the valid file descriptor on
non-Windows platforms.
