Ensure class_alias is only used for user-defined aliases.

Browse Source 
This commit finally does the (small) change that started this patch
series.

It ensures that the class_alias is only used for user-defined aliases.
So, the few GDB pre-defined aliases that were using the 'class_alias'
class are now using a real help class, typically the class of
the aliased command.
