Revert "package/pkg-autotools.mk: only pass --runstatedir=/run if supported"

This reverts commit cc9d55e19f564afc5a36be482329c43637252a6f.

This unfortunately still breaks with packages having additional configure
scripts in subdirectories where the toplevel script supports --runstatedir,
but some of the children do not.
