tools: bpf_jit_disasm: Add option to dump JIT image to a file.
When debugging the JIT on an embedded platform or cross build
environment, libbfd may not be available, making it impossible to run
bpf_jit_disasm natively.
Add an option to emit a binary image of the JIT code to a file. This
file can then be disassembled off line. Typical usage in this case
might be (pasting mips64 dmesg output to cat command):
$ cat > jit.raw
$ bpf_jit_disasm -f jit.raw -O jit.bin
$ mips64-linux-gnu-objdump -D -b binary -m mips:isa64r2 -EB jit.bin
