Removed protobuf patch in commit bc95679 actually fixes protobuf CMake configure failures for both jobs.

test-conda-python-emscripten failed because of retries and timeout 1h.
test-ubuntu-22.04-cpp-emscripten now shows preexisting arrow-utility-test failure which can be seen on nightly 2026-10-22 to 2026-10-26 already before protobuf failing started on 2026-10-27

The following tests FAILED:
	 41 - arrow-utility-test (Failed)
	 85 - arrow-substrait-substrait-test (Failed)
