Pahole v1.27 added a new BTF generation feature to support
reproducibility in the face of multithreading.
Enable it if supported and reproducible builds are requested.

As unknown --btf_features are ignored, avoid the test for the pahole
version to keep the line readable.

Fixes: b4f7278 ("scripts/pahole-flags.sh: Parse DWARF and generate BTF with multithreading.")
Fixes: 72d0918 ("kbuild: avoid too many execution of scripts/pahole-flags.sh")
