library generates stderr

[lacostej]

As seen in fastlane/fastlane#21668, we are observing error messages being printed out in the CI console

One way to reproduce this

require 'security'
name="match_https://github.com/fastlane/fastlane/tree/master/certificates"
Security::InternetPassword.delete(server: name)

Potential output:

 => false 

Maybe other methods do generate stderr as well.
