Subject: [PATCH] not display menu when boot once

References: bnc#771587
Patch-Mainline: no

We should prevent the menu from being displayed if boot once is
specified. This is in order to compliant with Grub1's behavior
and is better than current as it's not make any sense to bother
user to make decision when decision has been made.
