Fix issue with qstorageinfo_unix.cpp not working on Vxworks

Problem was, that qstorageinfo_unix.cpp is using sys/statvfs.h header, but this header is not available in Vxworks(Vxworks has
its own /sys/ directory).As this feature is not there in Vxworks, we are using a "_stub" file to omit whole implementation.
This is the same solution as it was used for Qt5 for Vxworks.
