tests/reproducible_build: Use --btf_features=all when encoding
Alan suggested:
"What about adding --btf_features=all as this would mean we'd be
encoding all the standard kernel features? we'd need to do the same
below in the thread loop. without that we're missing out on a few
features that the kernel builds use in BTF encoding, and we probably
want to ensure that we're testing as close to a real kernel BTF encoding
scenario as possible."
Do it.
