rust: rustdoc reproducibility issue fix

Browse Source 
The 'codegen-units' option split the crate into multiple compilation units for parallel compilation. Currently, this split is causing the rustdoc to generate differnt binary between the builds.
To fix this the codegen-units & the lto options are disabled.

More info about options:
