kbuild: rust: rename flag to `-Zdebuginfo-for-profiling` for Rust >= 1.98
Starting with Rust 1.98.0 (expected 2026-08-20), the
`-Zdebug-info-for-profiling` flag has been renamed to
`-Zdebuginfo-for-profiling` (i.e. one less dash, to match `debuginfo`s
in other flags) [1].
Without this change, one gets in the latest nightlies:
error: unknown unstable option: `debug-info-for-profiling`
Thus pass the right name.
