Use the correct `llvm-profdata` binary in `opt-dist`

Turns out that we were probably using the wrong `llvm-profdata` binary in the PGO script all along. This should resolve the performance regressions of switching the host LLVM to 17 ([host `llvm-profdata`](rust-lang/rust#114297 (comment)), [target `llvm-profdata`](rust-lang/rust#114297 (comment))]).
