Compile sauron on Debian 11 fails (workaround)

Rust version on Debian 11 to old => compile fails.

Workaround:

Install newer version of rust and some dependencies as follows

```
git clone https://github.com/evilsocket/sauron.git
cd sauron
sudo apt remove rustc-mozilla
sudo apt install curl build-essential gcc make libssl-dev libclang1 clang -y
# local user install of rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | s
source "$HOME/.cargo/env"
cargo build --release
```
