pw_protobuf: Fixes Python path on LUCI/presubmit

This change passes through the PATH environment variable to Bazel
allowing pw_env_setup to override the system Python installation. This
partially fixes pwbug/437 allowing for Protobuf/RPC rules to be run on
the CI and locally. This however introduces a dependency for
Pigweed/Bazel on pw_env_setup or system Python-3.6+ for downstream
projects.

Bug: 437
No-Docs-Update-Reason: Fixes build configuration.
