[PATCH 1/1] kernel-grub.bbclass: support /boot area within root partition

[Hongxu Jia]

Previously, it supported the situation that /boot area with separate boot
partition:
...
menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" {
    set root=(hd0,1)
    linux /bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp
}
...

But didn't consider the situation that /boot within root partition:
...
menuentry "Update bzImage-3.10.10-WR6.0.0.0_standard-3.10" {
    set root=(hd0,1)
    linux /boot/bzImage-3.10.10-WR6.0.0.0_standard root=/dev/sdb1 rw ip=dhcp
}
...

This fix supported them both.
