[OE-core][Patch 2/2] kernel-yocto.bbclass: force creation of config.queue

["Max Krummenacher" <max.oss.09@gmail.com>]

In the case of no patches or no configure fragments, during
do_kernel_metadata() scc is not called, and thus
kernel-sources/${meta_dir}/config.queue is not created.
Later do_kernel_configme fails because the file is missing.

| ERROR: Execution of 'run.do_kernel_configme.24874' failed with exit code 1:
| exit 1 from 'configs="$(scc --configs -o ${meta_dir})"'

Forcing at least an empty config.queue file fixes this.

Fixes: 23dcff0d396c (kernel/yocto: ensure that defconfigs are processed first)
