perl: warning: Falling back to the standard locale ("C")

Created by: philmmanjaro

We should set a locale so we don't have these warnings anymore:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_COLLATE = "C",
    LANG = "en_US.utf8"
    are supported and installed on your system.
