[OE-core] [PATCH v2] kernel-module-split: rrecommend kernel-image instead of rdepend

[Martin Hundebøll]

Hard depending on the kernel makes it impossible to install kernel
modules without getting the kernel image installed too. This is
inconvenient in e.g. initramdisks, where the kernel is loaded from
outside the initramdisk.

Making the kernel modules rrecommend kernel-image-<version> instead of
rdepending on it, makes it possible to install kernel modules without
the kernel image by setting "kernel-image" in BAD_RECOMMENDATIONS.
