[staging-next] python3Packages.home-assistant-chip-wheels: fix building with newer gn

[emilylange]

This fixes the following error caused by https://gn-review.googlesource.com/c/gn/+/18820 and the gn bump in b59bfde (#419337) by backporting https://pigweed-review.googlesource.com/c/pigweed/pigweed/+/300272

Running phase: configurePhase
gn flags: chip_project_config_include_dirs=\[\"//..\"\] chip_crypto=\"openssl\" [...]
  generated_file("$target_name._includes") {
  ^-----------------------------------------
Two or more targets generate the same output:
  protocol_buffer/gen/third_party/pigweed/repo/pw_chrono/protos.proto_library/includes.txt

This is can often be fixed by changing one of the target names, or by setting an output_name on one of them.

Collisions:
  //third_party/pigweed/repo/pw_chrono:protos._includes(//build/toolchain/custom:custom)

#432489
