OCPBUGS-65681: Oops, I forgot IBMCloud

In HIVE-2302 / #2729 we rearranged the way installmanager figures out
which platform-specific ConfigureCreds() function to call, but forgot to
include IBMCloud in the lookup table. (BareMetal is there, which we
don't use, and which is probably why this was missed, as it made the
number of entries correct.)
