Add cdb_supported to expected keys in test_sfp.py

[bgallagher-nexthop]

Description of PR

sonic-net/sonic-platform-common#721 adds a new key to get_transceiver_info called cdb_supported that indicates whether a transceiver advertises CDB support.

Summary:
Once sonic-net/sonic-platform-common#721 merges, cdb_supported will always be returned by CmisApi.get_transceiver_info. This test needs to be updated to reflect that or else it will fail.
