docker_build: Properly handle / as data_path

The handling in _compute_data_path would incorrectly result in an empty
strip_prefix being passed to _dest_path. The outcome was all files would
end up at the top of directory, instead of nested according to the
repository structure.

This change brings the behavior in line with the documentation, which
states:

> This path can be absolute from the workspace root if starting with a
> `/` or relative to the rule's directory.

Bazel (Beta)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
