The shipped .config files all have CONFIG_TICK_CPU_ACCOUNTING and
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE set. The x86_64 .config files
additionaly have CONFIG_VIRT_CPU_ACCOUNTING_GEN set.
This is wrong because each .config should have just one of these three
set. As a result the build generates
[...]⚠️ override: VIRT_CPU_ACCOUNTING_NATIVE changes choice state
24 times and
[...]⚠️ override: VIRT_CPU_ACCOUNTING_GEN changes choice state
4 times. So let's make sure the shipped .config files only have one of
these three Kconfig macros set (ie, the one that's relevant for that
.config target).
