MacOs dockerless: fork/exec /var/task/bootstrap: permission denied

[marijnhurkens]

🐛 Bug description

On MacOs using the dockerless function I get a permission denied error:

{"errorType":"exitError","errorMessage":"RequestId: 8ed9feed-c1a2-1705-f60b-4ca1d6303f50 Error: fork/exec /var/task/bootstrap: permission denied"}

 Serverless Error ----------------------------------------

  ServerlessError: Failed to run docker for rust image (exit code 1})

I'm using the master branch of this plugin because this should be solved in https://github.com/softprops/serverless-rust/issues/93

Cargo.toml

[package]
name = "test-serverless-rust"
version = "0.1.0"
edition = "2018"

[dependencies]
tokio = { version = "1.0", features = ["macros", "io-util", "sync", "rt-multi-thread"] }
serde = { version = "1", features = ["derive"] }
serde_json = "^1"

package.json

serverless.yml

service: test-serverless-rust
frameworkVersion: ^2.51
provider:
    name: aws
    runtime: rust
    memorySize: 128
    region: eu-west-1

package:
    individually: true

plugins:
    - serverless-rust

functions:
    test-serverless-rust:
        handler: test-serverless-rust
        events:
            -   http: 'ANY /'
            -   http: 'ANY /{proxy+}'
custom:
    rust:
        dockerless: true

And main.rs

use lambda_runtime::{handler_fn, Context, Error};
use serde_json::{json, Value};

#[tokio::main]
async fn main() -> Result<(), Error> {
    let func = handler_fn(func);
    lambda_runtime::run(func).await?;
    Ok(())
}

async fn func(event: Value, _: Context) -> Result<Value, Error> {
    let first_name = event["firstName"].as_str().unwrap_or("world");

    Ok(json!({ "message": format!("Hello, {}!", first_name) }))
}

I am running using serverless invoke local -f test-serverless-rust -d '{"firstName":"world"}'

🤔 Expected Behavior

The function to be built and invoked locally.

I have the same issue on Linux (Fedora 34)

@softprops can you please create a new release of the package? It will be really much more convenient for the end-users. Thanks in advance!
