Rename sanitizer runtime libraries on OSX
Currently we ship sanitizer libraries as they're built, but these names
unfortunately conflict with the names of the sanitizer libraries
installed on the system. If a crate, for example, links in C code that
wants to use the system sanitizer and the Rust code doesn't use
sanitizers at all, then using `cargo` may accidentally pull in the
Rust-installed sanitizer library due to a conflict in names.
This change is intended to be entirely transparent for Rust users of
sanitizers, it should only hopefully improve our story with other users!
Closes#54134
