Plotters: Improve visibility of runtime error messages from bladebit/madmax when invoked by `chia plotters`

[paninaro]

When querying which plotters are installed and which versions, if the plotter crashes when run with --version, we don't see the underlying issue. Instead, we just see that the plotter exited with a non-zero status code. We should improve the visibility of the error messages from the plotter so that the user has a clue of what the issue is (missing library dependency).

I've create a PR https://github.com/Chia-Network/chia-blockchain/pull/13704

How to test

• Prepare test executable which always fails and return non-zero.

  # bladebit.rs
  fn main() {
  panic!("test");
  }

• Compile it.

  $ rustc bladebit.rs
  # You'll get bladebit or bladebit.exe for Windows

• Copy the pseudo bladebit executable to venv/bin/ or venv/Scripts for Windows
• Then run chia plotters version with virtualenv.

Sample output

(venv) PS C:\Users\User1\...\chia-blockchain> chia plotters version
Failed to determine bladebit version: thread 'main' panicked at 'test', bladebit.rs:2:3
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
chiapos: 1.0.11
