rustfmt is not skipped for generated mod.rs

[hanabi1224]

After upgrading to v3, the imports in generated mod.rs are no longer in alphabetic order, thus cargo fmt -- --check command fails. Should it also include #![cfg_attr(rustfmt, rustfmt::skip)]? Thanks.

Unfortunately, adding #![cfg_attr(rustfmt, rustfmt::skip)] will make it impossible to include generated file in source

include!(concat!(env!("OUT_DIR"), "/p/mod.rs"));

There are two options here:

• sort imports in generated file (PR welcome)
• specify rustfmt option to skip files marked as @generated

Reopening until merged to stable branch.

Done.
