Bump golang to 1.11.0

It's that time of year again! Go 1.11 is released, time to use it.

This commit also

* removes our archive/tar fork, since upstream archive/tar
  is fixed for static builds, and osusergo build tag is set.

* removes ENV GO_VERSION from Dockerfile as it's not needed
  anymore since PR #37592 is merged.

[v2: switch to beta2]
[v3: switch to beta3]
[v4: rc1]

[v6: rc2]
[v7: final!]
[v8: use 1.11.0]
[v9: back to 1.11]
[v8: use 1.11.0]
