[OE-core] [PATCH] image/image-prelink/image-mklibs/sanity: Drop pointless EXPORT_FUNCTIONS

[Richard Purdie]

I'm sick of seeing people adding to EXPORT_FUNCTIONS in these classes
when they clearly have no idea what it does.

Worse, these uses of it are all broken, the naming is incorrect and
they do nothing. Lets remove them and try and preserve any remaining
part of my sanity.
