virUUIDFormat: s/VIR_UUID_RAW_LEN/VIR_UUID_BUFLEN/ in comment

The function takes raw UUID and formats it into string
representation. However, the comment mistakenly states that the
expected size of raw UUID buffer is VIR_UUID_RAW_LEN bytes. We
don't have such constant since v0.3.2~24. It should have been
VIR_UUID_BUFLEN.
