Fix travis setup to work with go modules

[joac]

Just to get the build passing again!

I followed:

and:

@joac I think you also need to sign the licence/cla agreement in order to make everything pass.

[hoenirvili]

@mitchellh Could you please review this?

[jefferai]

Unfortunately we need the CLA signed before we can proceed.

[hoenirvili]

@jefferai I know this PR is old, I could sign the CLA and then open a separate PR including these changes.

[joac]

Done, sorry for the delay

[hoenirvili]

@joac It stills says that the licence/cla is pending. Are you sure that you sign the agreement?

[joac]

I signed it, but is not updating :(

@jefferai How can this issue with the license can be resolved in order to merge this?

[jefferai]

Sorry about that, I've poked the responsible people, hopefully it will be resolved on Monday
