Revert some Go package updates.

This reverts commit 5f833e0495f00a72f8d34a63e8afbc531afdd22d through
681ac9a66c26d2c739e41f03228f8c63fc0df482.

It's not idiomatic to update Go packages independently of their users.
This reversion was approved by Efraim on #guix:

http://logs.guix.gnu.org/guix/2020-05-26.log

* gnu/packages/golang.scm,
gnu/packages/syncthing.scm,
gnu/packages/tls.scm: Revert.
