inherit: use local -x ECLASS (bug 676014)
Use local -x ECLASS, and also make __export_funcs_var a local variable,
since this is simpler than managing these variables as globals
(eliminates PECLASS and prev_export_funcs_var variables). As an
additional benefit, this prevents interference from ebuild variables
as reported in bug 656354 for the ECLASS variable.
