NFC test if rosetta debugserver exists before testing rosetta 

A fresh install of macOS does not have Rosetta 2 installed by
default; the CI bots are often in this state, resulting in a
test failure.  debugserver already hardcodes the filepath of
the Rosetta 2 debugserver; test if that file exists before
running the Rosetta test.
