Subject: [PATCH] add GRUB_CMDLINE_LINUX_RECOVERY for recovery mode

References: [openSUSE-factory] Has FailSafe or Safe Mode been removed
            permanently from 12.2? 
Patch-Mainline: no

We adapt the script a bit in order to support openSUSE's failsafe
booting mode. We don't use single user mode but with specific kernel
command line options decided in YaST. These command line could be
applied to grub2's recovery mode via the new setting
GRUB_CMDLINE_LINUX_RECOVERY.
