Format UUID strings correctly
Prior to this patch although GlobalPlatform specifies that TAs and such
are identified with UUIDs, we don't format them quite right when turning
them into strings. Per https://www.ietf.org/rfc/rfc4122.txt, there
should be another hyphen after the first two bytes of clockSeqAndNode.
Unfortunately, fixing this breaks compatibility between how TAs are
built, and when the OS loads them.
With this patch UUID string are formated with the additional hyphen as
for instance: f81d4fae-7dec-11d0-a765-00a0c91e6bf6
