bazel: Remove support for angle bracket includes

Fixes the following error:

fail: attribute includes: './' resolves to the workspace root,
which would allow this rule and all of its transitive dependents
to include any file in your workspace. Please include only what
you need.

Bazel's recommendation [1] is to use double quotes instead of
angle brackets.
