Joerg Bornemann 845d28cafb qmake: Ignore stderr when determining the macOS SDK version
If xcrun prints warnings or errors to stderr while determining the SDK
version, they become part of the SDK version string.  This then leads to
a qmake error.

Intentionally ignore stderr so that it is not treated as part of the SDK
version.

Pick-to: 5.15 6.2 6.3
