rpm macros: add %tmpfiles_create_package

I expect that this will be mostly obsoleted by transfiletriggers that
(I hope) we will soon add. But let's do this for completeness anyway.
I'm keeping the description of the macro a bit vague, since I expect
that it'll be changed when transfiletriggers are added.
