[Bug]: license in crates.io shows as "non-standard"

[jprendes]

Bug Description

Youki crates use "license-file" field in Cargo.toml.
Crates.io takes this to mean the crate uses a non-standard license, as "standard" licenses are meant to be specified with the "license" field.

Steps to Reproduce

Go to libcontainer in crates.io, and check the license in the crate's metadata (left side column).

Expectation

The license field in crates.io should show the Apache-2.0 license.
