gobject-introspection: Fix the license (add MIT)

As per upstream the license should also include MIT[1]. This is also
what Fedora Linux uses[2].

This should also address the problem with auto-generated scannerparser.h
file which has the following header:

/* Bison interface for Yacc-like parsers in C

/* As a special exception, you may create a larger work that contains
   part or all of the Bison parser skeleton and distribute that work
   under terms of your choice, so long as that work isn't itself a
   parser generator using the skeleton or a modified version thereof
   as a parser skeleton.  Alternatively, if you modify or redistribute
   the parser skeleton itself, you may (at your option) remove this
   special exception, which will cause the skeleton and the resulting
   Bison output files to be licensed under the GNU General Public
   License without this special exception.

   This special exception was added by the Free Software Foundation in
   version 2.2 of Bison.  */

Taking advantage of the Bison expcetion, more precisely the following fragment:

 "distribute that work under terms of your choice"

it should also be possible to reuse the MIT license tag for redistribution of that
work instead of adding the default GPLv3+ tag (which would otherwise be required
without using the special exception).
