objtool/rust: add one more noreturn Rust function for Rust 1.99.0

Starting with Rust 1.99.0 (expected 2026-10-01), `objtool` may report:

    rust/kernel.o: warning: objtool: _R..._6kernel3str9parse_intaNtNtB2_7private12FromStrRadix14from_str_radix()
    falls through to next function _R..._6kernel3str9parse_intaNtNtB2_7private12FromStrRadix16from_u64_negated()

due to calls to the `noreturn` symbol:

    core::num::from_ascii_bytes_radix_panic

The function was renamed from `from_ascii_radix_panic` [1], which is
already in the list.

Thus add the new one to the list so that `objtool` knows it is actually
`noreturn`.

See commit 56d680dd23 ("objtool/rust: list `noreturn` Rust functions")
for more details.
