Have nightly gpu tests use system rather than bundled LLVM

This is because we're getting tons of errors when using the bundled LLVM 14 (see https://chapel.discourse.group/t/cron-cray-cs-gpu-native/12575/2). I don't believe we would get these issues when using LLVM 13 (the system LLVM). We were using the bundled LLVM for this testing configuration as we added it before we had system LLVM's, so we may want to make this a permanent change.
