test.bash: download dependencies

Browse Source 
Use module support in Go1.11 to download the exact version of dependencies
as specified in the go.mod file, this is contrary to "go get -u", which grabs
the latest version, making reproducible builds and tests difficult.

In order for Go1.9 and Go1.10 to work, we also emit a vendor directory for
pre-module support.

Lastly, check whether the go.mod or go.sum files changed
(by shelling to "git diff"). This provides protection in case
a new dependency was added and the go.mod file was not updated.
