[PATCH v2 3/3] rust: reproducibility issue fix with v1.76

[Yash.Shinde@windriver.com]

From: Yash Shinde <Yash.Shinde@windriver.com>

A few crates are using the updated version of the 'cc' crate and
this is causing the generated object file names containing a unique hashmap id.
The hashmap addition to generated files is reverted here.
