Rollup merge of #61250 - rye:print-target-list--rm-ios-case, r=alexcrichton

Remove special case for *ios* builds in run-make-fulldeps/print-target-list Makefile

Previous `TODO` comment in this file mentions [an issue that was closed](https://github.com/rust-lang/rust/issues/29812), and I was able to confirm locally that provided code in that issue no longer produces an ICE. Discussion on that issue seems to indicate this code was no longer needed as of 1.12.0.

I removed the `*ios*` branch from this `case` statement as it may cause confusion, then removed the case statement entirely as it only had a wildcard branch.
