Subject: [PATCH] docker: build with explicit go version

It is occasionally useful to assert that our output was built with >=x
version of the Go compiler or linked against >=x version of the Go
standard library.  While it is possible to make this assertion after the
fact -- say, by dumping the value of runtime.buildVersion with a
debugger -- it's usually much easier to inspect this file.
