rust: Fix BOOTSTRAP_CARGO failure during Rust Oe-selftest
BOOTSTRAP_CARGO command fails due to codegen flags like `-Cpanic` were
prevented from being reflected in the current target configuration which
leads to Rust build(rust version 1.70) failure in Oe-selftest.
Upstream-Status: Backport [https://github.com/rust-lang/rust/commit/9dffb52738e0b2ccd15af36d4607a709b21e020c]
