LICENSE: add GPLv2 license option.
As per the MCTP design document
(https://github.com/openbmc/docs/blob/master/designs/mctp.md), a
dual-licence (GPLv2+ and Apache-2.0) gives us flexibility with including
libcmtp code into various firmware environments.
This change adds GPLv2+ as a license option. All current contributors
have agreed to this change.
