mkosi: Rework kconfig handling

Browse source 
Instead of relying on the arch specific kconfigs that enable all
kinds of options that are irrelevant for our use case, let's beef
up our own config a little so that we don't need to rely on the
arch specific configs anymore.

Also, instead of using scripts/config to enable options in the
mkosi build script, let's add a new kernel.config file that includes
all the configs we want enabled/disabled.

Finally, let's make sure we can properly run the bpf selftests by
making sure we enable all the right configs required to run the bpf
selftests successfully. We use the scripts/kconfig/merge_config.sh
script to merge the three different config files together.
