rust: reproducibility issue fix

The '--remap-path-prefix' option removes all references to build directory
structure in the debug information within the compiled output for Cargo
dependencies and the project's binary.

However, some references to build directories remains in the final binary
in .rustc section in the form of compressed metadata and this makes the
build output dependent on the folder structure of the computer it's compiled on.

So, for reproducible builds, use the configuration option
'remap-debuginfo = true' along with the '--remap-path-prefix'.
