[pkg-go] RFS: new upstream snapshot golang-github-erikdubbelboer-gspt

[Michael Hudson-Doyle]

Hi all,

For some reason or other, Ubuntu builds don't have a tty and debian
builds do. golang-github-erikdubbelboer-gspt failed tests in this
situation, so I fixed this upstream:

   https://github.com/erikdubbelboer/gspt/pull/6

and pushed the new upstream snapshot to git.debian.org. Can someone
tag and upload pls?

Cheers,
mwh
