[PATCH] ktest: take submenu into account

[Satoru Takeuchi]

grub-reboot selects the submenu's first menuentry (title is "1>0") rather than ktest's
menuentry (title is "2") by mistake.

===
$ sudo cat /boot/grub/grub.cfg  | grep -E "^menuentry|^submenu"
...
menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option '...' {
...
submenu 'Advanced options for Ubuntu' $menuentry_id_option '...' {
...
menuentry 'ktest' {
...
===

Correct it by taking submenu entries into account in get_grub2_index().
