fixits: handle duplicates of %name-prefix

Browse Source 
The test case "Deprecated directives" (currently 56) no longer emits
warnings after 'bison -u'!

* src/files.h, src/files.c (spec_name_prefix_loc): New.
* src/parse-gram.y (handle_name_prefix): Emit fixits for duplicate
%name-prefix.
* tests/input.at (Deprecated directives): Adjust.
