Rollup merge of #136938 - mustartt:fix-stack-protector-filecheck, r=Mark-Simulacrum

Remove `:` from `stack-protector-heuristics-effect.rs` Filecheck Pattern

With function sections, the assembly label does not necessarily end in `:`.

Remove trailing `:` to be more consistent with the rest of the existing Filecheck patterns.
```
// CHECK-LABEL: local_string_addr_taken
#[no_mangle]
pub fn local_string_addr_taken(f: fn(&String)) {
    let x = String::new();
    f(&x);
```
