Disable Rust tests that fail for benign reasons with LLVM 17.

tests/ui/abi/stack-protector.rs:
rust-lang/rust#109671 the test is being
optimized in newer LLVM which breaks its expectations.

tests/ui/backtrace.rs:
rust-lang/rust#109672 the second panic in a
double-panic is being optimized out (reasonably correctly) by newer
LLVM.
