gen_configkernel.sh: determine_kernel_config_file(): Add kconfig containing KERNEL_LOCALVERSION to kconfig candidate list
Since we added $ARCH to KERNEL_LOCALVERSION by default,
$KV from fresh kernel sources won't match with saved kernel
config file anymore which will break kernel upgrades when
saved kernel config file was just copied to new kernel
version without removing LOV part.
WIth this commit we still prefer extracted $KV when looking
for kernel config file, however, we will also look for
kernel config file where $KV contains KERNEL_LOCALVERSION
we are going to use in addition.
