winpr: fix PathMakePathA and TestWLog

PathMakePathA:
- This function had an endless loop if no native delimiter was in the string
- Use SHCreateDirectoryExA on Windows
- Replaced old code with a new implementation

TestWLog:
- Windows has no "/tmp" by default
- Use GetKnownPath(KNOWN_PATH_TEMP) for the WLog "outputfilepath"
