[dmidecode] [PATCH v2 3/4] dmioem: Use product name to determine Generation.

[Jerry Hoemann]

Generally, HPE OEM records are extended by adding additional
fields at the end or record and increasing the length.  But,
this isn't always the case and will less likely be so going
into the future.

Determine the generation of the HPE OEM records by examining
the "Product Name" string.
