s/ULONG_MAX/UINT_MAX/

to silence a compiler warning, and to deal with the fact that even
though this function populates an 'unsigned long *version', the only
reason it does so is because of our (poor) choice in making
virGetVersion use unsigned long.  But for portability to 32-bit hosts,
we can never exceed a 32-bit version computation, even on hosts where
long is 64-bits.
