overlay sys-kernel/coreos-modules: Enable mmc_block as a module

Enables the mmc_block driver reported missing in flatcar/Flatcar#1300

How to use

• Install flatcar to hardware with eMMC drive slot (will be tested once built).

Testing done

• None yet

I've tested it with the 6.1 kernel and it doesn't seem to hurt adding it explicitly but I wonder why the module was not found in your case - maybe in the initrd it's missing?
Edit: Yes, missing in the initrd is the problem we need to solve here

We need to add mmc_block in the bootengine repo https://github.com/flatcar/bootengine/blob/flatcar-master/update-bootengine#L37 and then update the ebuild file ref here in sdk_container/src/third_party/coreos-overlay/sys-kernel/bootengine/bootengine-9999.ebuild
