Reset to the text console before exiting grub2 (bsc#1248167)

The 'Boot from Hard Disk' menu entry exits grub2 and gives back the
control to the system firmware, e.g. BIOS or UEFI. Without resetting the
terminal output to the text console, SeaBIOS may not clean up the screen
and output messages correctly.
