[PATCH] programs/winetest: Report GetLastError() when CreateProcess() fails.

Sometimes httpapi_test.exe fails to run but in such a case the only
information we get in the report is the run_ex() return code, -2, which
does not tell us anything about what happened:
https://test.winehq.org/data/patterns.html#httpapi:httpapi

With this patch the done line will contain the GetLastError() value
which I expect to be ERROR_FILE_NOT_FOUND (2) due to the anti-virus
quarantining our test executable.

So 'done (-2)' will be replaced by 'done (-2)' and that changes
everything ;-). I may even get 'done (-3)' one day. Weeeee!

More seriously. This value is overloaded quite a bit:
* It can be the test's exit code (a failure count).
* Or an exception 'exit code' (e.g. c0000005 -> -1073741819).
* Or a WaitForSingleObject() return value (typically 258).
* Or the CreateProcess() -GetLastError() (expecting -2 here).
But that's probably still fine.
