Add --no-std switch to verilator

[PiotrZierhoffer]

@tcal-x can you please verify if this fixes the problem for you?

Hi @PiotrZierhoffer , thanks! --- that did fix the issue I saw running "make renode" manually, but there are many failing tests now?

[PiotrZierhoffer]

It stems from the fact that the CI uses older verilator.

Let's [WIP] this - we'll change the package to implicitly provide this switch, so that the user interface doesn't change.

If I recall correctly, we originally added Verilator to the list of Conda packages used because the version that we got from sudo apt install verilator in Google Colab (Ubuntu 18) was too old.

I thought all of the Github Actions now relied on the Conda packages, which should hide an older system version of Verilator?

[PiotrZierhoffer]

We made some changes to the verilator conda package, as it was failing the build on GCP.

We need to update it a little bit further to address this use case, I believe.

@PiotrZierhoffer sorry if I dropped the ball here -- what is the status of this?
