bpf, arm64: Feed byte-offset into bpf line info
insn_to_jit_off passed to bpf_prog_fill_jited_linfo() is calculated in
instruction granularity instead of bytes granularity, but BPF line info
requires byte offset.
bpf_prog_fill_jited_linfo() will be the last user of ctx.offset before
it is freed, so convert the offset into byte-offset before calling into
bpf_prog_fill_jited_linfo() in order to fix the line info dump on arm64.
