updating QEMU parameters and default path for the firmware

[AlissonMachadoEmbitel]

Hello,

I was facing a couple of issues when trying to run it on MacOS, then I made these fixes.

It was the same problem related on this issue: #1028

Hey @AlissonMachadoEmbitel thank you very much for your contribution! Couple of things:

1. We use commit signing in, so all of our commits are signed by authors, you can easily do that by running

git commit --amend  --signoff

2. Could you please tell me what qemu version are you using?
   You can do it by running if you installed it with brew or you have qemu binary in your PATH

qemu-system-x86_64 --version

Hi @uncleDecart ,

This is my current version:

➜ ~ qemu-system-x86_64 --version
QEMU emulator version 9.2.2

I think it's a valid concern and I've seen this issue before, but it works on my combo QEMU 10.0.2 on Linux.
@shjala did you face something similar on macOS?

@europaul I run things on a remote linux machine.
