Setup Github Actions CI (hound-search#354)

* Setup Github Actions CI

Replaces Travis CI with Github Actions for better integration.
Jobs are run against more recent Go versions, namely 1.12 to 1.14 .
 .
For further documentation see

- https://github.com/actions/setup-go
- and https://help.github.com/en/actions

This adds `-race` flag to the Go tests and will run a meta linter
(golangci-lint).

* keep travis in until github workflows is tested

* tidy go mods

* remove lint command from github workflow

* add back go-bindata to go modules list

* up version of actions checkout to fix deprecation errors

* return go bindata to the go.sum file as well
