gconv.h: fix build with GCC 7
gconv.h is using a flex array to define the __gconv_info member in an
invalid way, causing GCC 7 to issue an error:

This is basically a revert to the code from 15 years ago. More details
are available in the GCC bug:

Changelog:
* iconv/gconv.h (__gconv_info): Define __data element using a
zero-length array.
