[test]: Update VS portchannel tests to remove static conf file

Currently, the teamd configuration is no longer used in SONiC. The
configuration is dynamically generated and stored in the configuration
database, which is picked up by the teammgrd.

To create new portchannels, and the members, the command:
config portchannel add
config portchannel member add
are used.
