[roll third_party/pigweed] pw_env_setup: Improve cipd_repository error handling

Improves the robustness of the cipd_repository repository rule in the
Bazel build.

 - Uses the relative path to the fetched CIPD binary rather than
   assuming CIPD is present on the PATH.
 - cipd_repository will now emit errors if `cipd ensure` fails.
 - File globs include all files in the repository rather than just files
   in subdirectories of the repository.
