The module_layout symbol is a special case that is always kept exported,
even with CONFIG_TRIM_UNUSED_KSYMS=y.
task_struct is special in a different way. It can be accessed without
the use of an exported symbol through direct register access.
Add them to the global whitelist to ensure they are kept stable.

Now that GKI comes without modules, the GKI whitelist is effectively
empty as GKI itself would not require any stable symbols any longer.
Hence, clear out the main whitelist and ABI representation. In
subsequent changes I will extend the additional whitelists to bring back
the actually used symbols.
