Update to the latest upstream version and add a patch that enables pahole
reproducible builds if SOURCE_DATE_EPOCH is defined in the environment.
This patch helps avoid BTF-related module loading problems with packages
built separately from the kernel such as mac80211 or kselftests-bpf, e.g.:
[ 16.858856] BPF: type_id=1185 bits_offset=0
