Update Docker files and remove references to gb (#703)

Fix Docker files which had been forgotten in #594 and update scripts and docs to remove references to gb.

I also removed the `jenkins` directory which is outdated. We can revert f8d7e99 if we realise that it was a mistake to do so.

+As of May 2019, we're not using `gb` anymore, which is the tool we had been
+using for managing our dependencies. We're now using Go modules. To build
+Dendrite, run the `build.sh` script at the root of this repository (which runs
+`go install` under the hood), and to run unit tests, run `go test ./...` (which
+should pick up any unit test and run it). There are also [scripts](scripts) for

-Dependencies are located in `vendor/src` and are managed by `gb`. If you need
-to make some changes in those directories, you first need to open a PR in the
-dependency repository. Once your PR is merged, you need to run `gb vendor

-in the dendrite repository to update the dependency.

-You can then create a commit containing only the modified vendor files (along

-`gb vendor update github.com/matrix-org/gomatrix`), and open a PR on Dendrite.
