meta: drop redundant export syntax

There are quite a few 'export' syntax, they are either not necessary or
being redundant. Actually only the variables being referred in ostree
or aktualizr need to be exported, we can move them into sota.bbclass so
they can be exported once only for all other classes referring to them.

And drop all other unnecessary exports.
