Removing absolute path in proc-macro

With rust 1.75 the absolute build path is embedding into '.rustc' section and which causes reproducibility issues. Detailed issue is here.
https://github.com/rust-lang/rust/issues/120825#issuecomment-1964307219

With this change the 'absolute path' changed back to '/rust/$hash' format.
