Use version --nognu_format for the bootstrap test

The SOURCE_DATE_EPOCH is put into the version data we bake into the binary as the build timestamp, which is only available in --nognu_format. This is in preparation for switching to --gnu_format by default.

We should consider changing compile.sh to put in a more useful stamp than the current output, which is 'bazel 0.23.2- (@non-git)', but that's independent of this change.

Note that current bazel version output looks like this:
Build label: 0.22.0
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Mon Jan 28 12:58:08 2019 (1548680288)
Build timestamp: 1548680288
Build timestamp as int: 1548680288

Progress on #3599.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel only rebuilds what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
