Description of problem:
When running HTS R32 on a DIYed machine, HTS can not find system's model, this
leads to an error when running "hts submit". Can we provide some default
values(e.g.: "unknown") to "vendor" and "model" and "make" if the harness can
not find them from system's BIOS, because for some machines(especially for some
DIYed machines), these three info may not always be available(though we can find
them on most IHV's machines).  

Following are error logs:
