Subject: [PATCH] Work-around for Cargo download dependency failed

This is a work-around for charm build failures resulting in:
"Cargo download dependency failed "send: no filter connected".

This is documented in the following upstream issue:
https://github.com/rust-lang/cargo/issues/12202

This affects lunar builds where the curl version is 7.88.1.

Thanks to Colin Watson for help with figuring this out.
