[PATCH 3/3] rust: pin-init: feature-gate the `stack_init_reuse` test on the `std` feature

[Benno Lossin <lossin@kernel.org>]

From: Benno Lossin <benno.lossin@proton.me>

When trying to run `cargo check --all-targets --no-default-features`, an
error is reported by the test, as it cannot find the `std` crate. This
is to be expected, since the `--no-default-features` flag enables the
`no-std` behavior of the crate. Thus exclude the test in that scenario.
