fix byte ordering in check_sysid

fix byte ordering in check_sysid

Several uuid fields as well as the ip addreses in the sysid file are in
network byte order.  Fix the check_sysid utility to decode these fields
properly.  In addition, print the server uuid in the common string
format used to display uuids, instead of by individual uuid fields.

(cherry picked from commit 52b8073a6c1ef11f1a47fb26d77efd87425be556)

Note: Although this fix is marked as a "cherry-pick", this patch was
rewritten for the 1.6 branch since the opr uuid handling functions are
not available in the 1.6 branch.
