rustbuild: Disable ThinLTO for libtest

alexcrichton · alexcrichton · commit f6cc9ee7ad2d · 2017-11-10T01:39:07.000-08:00
Right now ThinLTO is generating bad dwarf which is tracked by #45511, but this is causing issues on OSX (#45768) where `dsymutil` is segfaulting and failing to produce output. Closes #45768
