profile_trim_paths::lldb_works_after_trimmed requires elevated privileges on macOS

[ehuss]

The test profile_trim_paths::lldb_works_after_trimmed causes an authentication popup to show on macOS. This is because macOS requires elevated privileges to run developer tools. I think it would be good to avoid that when running in a developer environment.

Unfortunately I don't think there is an easy way around that. My only idea is to disable the test on macOS unless it is running on CI.
