configure.ac: Detect wchar_t using wchar.h header

Browse Source 
The wchar_t type is defined in `wchar.h` and if this header is not
included by autoconf the detection of the type will fail.  This type is
required by `unicharset_extractor` to autogenerate the character
properties.

This problem was detected when running under Fedora 21.
