[recipes] Don't show unset prep/cook time

[Matthias Clasen <matthiasc src gnome org>]

commit 18b4b09a808e4b2847ba54ef4adf4ef5ac09751a
Author: Matthias Clasen <mclasen redhat com>

    Don't show unset prep/cook time
    
    Showing empty fields for these does not really add anything,
    so hide them if they are not set.
