d: handle eof in yytranslate

Browse Source 
This changes the traces from

    Reading a token:
    Now at end of input.

to

    Reading a token:
    Next token is token $end (7FFEE56E6474)

which is ok.  Actually it is even better, as it gives the location
when locations are enabled, and is clearer when rules explicitly use
the EOF token.

* data/skeletons/lalr1.d (yytranslate_): Handle eof here, as is done
in lalr1.cc.
