cmd/compile: stop treating interface methods like actual functions

Browse Source 
Interface methods can't have function bodies, so there's no need to
process their parameter lists as variable declarations. The only
possible reason would be to check for duplicate parameter names and/or
invalid types, but we do that anyway, and have regression tests for it
(test/funcdup.go).
