examples fail with error

[evanrolfe]

I've tried both the xdp-hello and tc-egress examples, following the instructions on the readme and they both fail with the same error when I run: cargo xtask run:

thread 'main' panicked at 'failed to run the command: Os { code: 2, kind: NotFound, message: "No such file or directory" }', xtask/src/run.rs:65:10
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

By default, the runner will append the sudo -E to the run command (for instance, the xdp-hello: https://github.com/aya-rs/book/blob/main/examples/xdp-hello/xtask/src/run.rs#L17). So if you run it as root and sudo command does not exist, you will get that error.

One workaround is to specify the -r option with an empty string:
RUST_LOG=info cargo xtask run -r ""
