Cannot compile project with only `bundled` and `theseus` features and problem with not working `bundled` feature

[qarmin]

What steps will reproduce the bug? (please provide code snippet if relevant)

1. Create project with this Cargo.toml

[package]
name = "testy"
version = "0.1.0"
edition = "2021"

[dependencies]
postgresql_embedded = { version = "0.19.0", default-features = false, features = ["bundled", "theseus"] }

2. main.rs

use postgresql_embedded::{PostgreSQL, Settings};

fn main() {
    let settings = Settings::default();
    PostgreSQL::new(settings);
}

3. cargo check and cargo check --release fails with info

error: failed to run custom build command for `postgresql_embedded v0.19.0`

Caused by:

Enabling the rustls feature fixes the problem, but I don't want to use this feature.
It seems that even with the bundled feature enabled, PostgreSQL.setup() still tries to download images from the internet.
(This might be our fault because maybe we download a different version than the one used at runtime — but still, internet access should be disabled when the bundled feature is enabled)

Maybe rustls and native-tls should be split into separate build-time and runtime(rustls-build, rustls-runtime, native-tls-build, native-tls-runtime) features to avoid such situations.
