Move last error into memory

These changes move the `Evaluator::last_error` into miri's memory and implement the `__errno_location()` shim (which is used by the file handling functions when they fail).

Write name and value for each env var

In order to res0lve https://github.com/rust-lang/miri/issues/756 is necessary to have the whole `"NAME=VALUE"` sequence of bytes written into memory instead of just the value.

This change does not affect the interface of the `shim::envs::EnvVars` type in any way.

Use host's rng when communication is enabled

This uses the host's randomness when the communication enabled flag is used. I am not sure about the error handling. I was thinking about fallbacking to `rand` if `getrandom` fails and also print something so the user knows miri is not using the host's rng because it failed. Let me know what you think.
