[PATCH 2/2] sadump: convert the first three fields of EFI GUID from little-endian into big-endian

[d.hatayama@xxxxxxxxxxxxxx (HATAYAMA Daisuke)]

Although RFC 4122 recommends network byte order for all fields of
UUID, EFI GUID uses little-endian for the first three fields TimeLow,
TimeMid and TimeHighAndVersion. Thus, in text representation of the
GUID, converting the three fields from little-endian into big-endian
is needed.
