Fix a memory overflow in lib/uuid.c:is_base_uuid128.

According to the man page, scanf's %[] operator writes to the provided
character buffer the number of characters in the capture (1 in this
case), as well as a terminating NUL byte.  asan agrees that we were
trying to write two bytes into one byte of storage.  This change makes
the temporary buffer large enough to accommodate the NUL.
