Log Message:

buildRustPackage: Fix "warning: file ... may be generated" (#24471)
Every Rust derivation used to emit a warning like the following:
```
setting SOURCE_DATE_EPOCH to timestamp 1490877042 of file
cargo-6e0c18c/Cargo.lock
warning: file cargo-6e0c18c/Cargo.lock may be generated; SOURCE_DATE_EPOCH may
be non-deterministic
```
The reason is that the dependencies are copied without preserving
timestamps. Changing the build script to timestamp-preserving copy
removes the warning.
