unidata: don’t check special casing in unidata-check (bug#26656)

* admin/unidata/unidata-gen.el (unidata-check): Do not test special
casing mapping of characters since that mapping is not constructed from
the unidata.txt file.
Also, check for integer decoder and cons char earlier so that less
unnecessary processing is performed.
