please remove this package from bionic

[Michael Hudson-Doyle]

Go 1.8 has been unsupported since the release of Go 1.10 a month or so ago and should be removed from bionic before release.

mwhudson@aeglos:/opt/opensource$ reverse-depends src:golang-1.8
No reverse dependencies found
mwhudson@aeglos:/opt/opensource$ reverse-depends -b src:golang-1.8
Reverse-Build-Depends
=====================
* go-dep (for golang-1.8-go)
* ncbi-entrez-direct (for golang-1.8-go)

Both of those packages use "golang-any (>= 2:1.8~2~) | golang-1.8-go"-type constructions and so will be unaffected by the removal.
