eclasses.tex: Clarify precedence of EXPORT_FUNCTIONS calls
Clarify that the last call to EXPORT_FUNCTIONS takes precedence over
earlier calls.
Unfortunately, we need an exception when inherit is called after
EXPORT_FUNCTIONS because Portage changed its behaviour in 2009:
https://gitweb.gentoo.org/proj/portage.git/commit/?id=06d4433e8b8be60d606733b9e23f57f8a5869d8f
Pkgcore and Paludis apply precedence consistently based on call order
of EXPORT_FUNCTIONS.
