Build instructions for MacOs X in readme

[Filter94]

It seems to be missing instructions for MacOs X, but I can see that on Cirlce CI the MacOs workflow is building the project.

Can you please add it?

mac os has just recently updated and didn't work. I just fixed it now.

Can you confirm that this instruction set is working?

do you use latest retesteth/develop branch?

here

git clone git@github.com:ethereum/retesteth.git
cd retesteth
git fetch origin
git checkout develop

because the instruction set is for release. so would not need to checkout develop branch
