py_proto_library: fix for --legacy_external_runfiles=True
Previously, the import path within the runfiles was only correct for the case
--legacy_external_runfiles=True
(which copied the runfiles into$RUNFILES/<main repo>/external/<external repo>/<path>
in addition to$RUNFILES/<external repo>/<path>
. This flag was flipped to False in Bazel 8.0.0.This is identical to the change made to rules_python in bazelbuild/rules_python#2516.
Work towards bazelbuild/rules_python#2581.
