  2. bpf, arm64: call build_prologue() first in first JIT pass 

    BPF line info needs ctx->offset to be the instruction offset
in the whole jited image instead of the body itself, so also
call build_prologue() first in first JIT pass.

  3. bpf, arm64: calculate offset as byte-offset for 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, so fixing it by calculating ctx->offset
as byte-offset. bpf2a64_offset() needs to return relative instruction
offset by using ctx->offfset, so update it accordingly.
