package/libs/libiconv: function names

Currently libiconv-stub and libiconv-full use different names
for functions iconv, iconv_open, and iconv_close.

This may lead to failures when building modules, e.g. with
apr-util when NLS is not activated.

The two modules libiconv-stub and libiconv-full should be
interchangeable, so we need the same function names.

After applying this patch execute

	make distclean
