Fix UUID random generator to use /dev/random

Browse Source 
Only use pseudo-random generator for uuid if using /dev/random fails.
* src/util/uuid.c: The original code. would only print the warning
  message if using /dev/random failed, but would still go ahead and call
  virUUIDGeneratePseudoRandomBytes in all cases anyway.
