ANDROID: pahole -J -j1 for reproducible BTF, again

Versions of pahole from 1.22 support multi-threaded operation with
separate CUs being processed independently. This results in
non-deterministic and effectively non-reproducible output for kernel
objects. Later versions of pahole aim to support determinism by
retiring CUs in order.

We regain determinism by restricting parallelism to 1 at the cost of
some performance.

This is a repeat of commit a1e6a310 which got obliterated during
merge conflict resolution of commit 01c5dfca. It has also been
extended to cover later versions of pahole.
