[PATCH] kernel-grub.bbclass: use KERNEL_PACKAGE_NAME for the image packages

["prasanth" <ragaprasanth@gmail.com>]

kernel-grub adds its scriptlets to kernel-image-<type>, but kernel.bbclass
names these packages ${KERNEL_PACKAGE_NAME}-image-<type>. With another
KERNEL_PACKAGE_NAME the scriptlets go to a package that does not exist,
so they never run and the GRUB menu is not updated on a kernel upgrade.

Use KERNEL_PACKAGE_NAME, as kernel.bbclass and linux-dummy.bbclass do.

Notes:
    Checked with bitbake -e: with KERNEL_PACKAGE_NAME set, the GRUB
    scriptlets were set on kernel-image-<type>, which is not in PACKAGES. With this
    patch they are on <KERNEL_PACKAGE_NAME>-image-<type>; the default is unchanged.
