[libgpiod][PATCH] bindings: rust: remove useless clone

[Erik Schilling <erik.schilling@xxxxxxxxxx>]

Reported by 1.74.0-nightly:

  warning: call to `.clone()` on a reference in this situation does nothing
    --> libgpiod/tests/line_request.rs:71:44
     |
  71 |             let chip_name = sim.chip_name().clone();
     |                                            ^^^^^^^^ help: remove this redundant call
     |
     = note: the type `str` does not implement `Clone`, so calling `clone` on `&str` copies the reference, which does not do anything and can be removed
     = note: `#[warn(noop_method_call)]` on by default
