Dmitry Savintsev 96b282d149 aya-tool: remove outdated workaround
The comment says that `.derive_debug` was needed as
a workaround for https://github.com/rust-lang/rust-bindgen/issues/2083.
This issue is now closed, and aya-tool compiles without derive_debug.

Additionally, update bindgen dependency to 1.64.
