Assign ASCII-Latin8 to dbus-sdr FRU string Type/Len

The FRU ID string Type/Len encoding in the dbus-sdr code is left
unassigned, which causes it to be tagged as unicode characters. This
is not the encoding of the data, which is actually ASCII/Latin8.

The problem appears to go unnoticed, I expect, because the dbus-sdr
functionality is not enabled. When dbus-sdr is enabled the id-string
supplied to IPMITool is ASCII/Latin8, but IPMITool decodes it as
unicode.

Tested:
Enabled dbus-sdr features.
Use 'ipmitool fru print'
Confirm FRU id-strings print as ASCII/Latin8
