multilib_global.bbclass: fix parsing error with no kernel module split

The problem could be reproduced with the following settings:
MACHINE = "qemux86-64"
KERNEL_SPLIT_MODULES = "0"
require conf/multilib.conf
MULTILIBS ?= "multilib:lib32"
DEFAULTTUNE:virtclass-multilib-lib32 ?= "core2-32"

The error message is as below:
  bb.data_smart.ExpansionError: Failure expanding variable KERNEL_VERSION_PKG_NAME, expression was ${@legitimize_package_name(d.getVar('KERNEL_VERSION'))} which triggered exception TypeError: expected string or bytes-like object
  The variable dependency chain for the failure is: KERNEL_VERSION_PKG_NAME -> RPROVIDES:kernel-modules

This is because multilib_virtclass_handler_global function in
multilib_global.bbclass deletes KERNEL_VERSION. So we need to handle
such situation. We'll also need to delete KERNEL_VERSION_PKG_NAME
to avoid this parsing error.
