config_whitelist: remove bogus options

These are not CONFIG options (detected by my eyes).

CONFIG_SPL_BUILD and CONFIG_TPL_BUILD are build options defined only
for building SPL and TPL, respectively.

The others are just mentioned in comment blocks.

Now, scripts/build-whitelist.sh never picks up new options.  Once
we kill these false ones, they will never revive.
