buildRustCrate: Make CARGO_MANIFEST_DIR absolute

Browse source 
While it is not obvious from the source, cargo sets CARGO_MANIFEST_DIR to an absolute directory. This let to a build problem with the popular "tera" crate using the "pest" crate.

## Cargo details

The variable is set here:

f7c91ba622/src/cargo/core/compiler/compilation.rs (L229)

and computed from the `manifest_path`:

f7c91ba622/src/cargo/core/package.rs (L163)

The manifest path is also exported via `cargo metadata` where you can see that it is absolute.
