Auto merge of #9891 - cengizIO:master, r=ecoal95

Replace deprecated fs::walk_dir call with walkdir crate

While working on #8351 I discovered that deprecated fs::walk_dir is used in android support files.

This is my first PR to any Rust project, so any constructive feedback is more than welcome!

Thanks
