kbuild: rust: re-run Kconfig if the version text changes
Re-run Kconfig if we detect the Rust compiler has changed via the version
text, like it is done for C.
Unlike C, and unlike `RUSTC_VERSION`, the `RUSTC_VERSION_TEXT` is kept
under `depends on RUST`, since it should not be needed unless `RUST`
is enabled.
