This adds support for generating bpf line info for JITed programs
like commit 6f20c71d8505 ("bpf: powerpc64: add JIT support for bpf
line info") does for powerpc, but it should pass the array starting
from 1 like x86, see commit 7c2e988f400e ("bpf: fix x64 JIT code
generation for jmp to 1st insn").
That fixes test_btf.

programs"
V1->V2:
- pass address array starting from element 1.
V2->V3:
- Fix braces in the commit message.
