clippy_lints: Do not warn against Box parameter in C FFI

changelog: [`boxed_local`]: don't lint in `extern fn` arguments

Fixes #5542.

When using C FFI, to handle pointers in parameters it is needed to
declare them as `Box` in its Rust-side signature. However, the current
linter warns against the usage of Box stating that "local variable
doesn't need to be boxed here".

This commit fixes it by ignoring functions whose Abi is C.
