copr: fix deprecation warning about evaluating devel as a bare variable

[DEPRECATION WARNING]: evaluating devel as a bare variable, this
    behaviour will go away and you might need to add |bool to the expression
    in the future. Also see CONDITIONAL_BARE_VARS configuration toggle..
    This feature will be removed in
     version 2.12. Deprecation warnings can be disabled by setting
     deprecation_warnings=False in ansible.cfg.
