glr2.cc: also run all the calculator tests

Having looked at calc.at for Adela's report, I noticed that glr2.cc
does not run all the calc tests.  They uncovered a few issues.  The
good news is: fixing them simplifies the skeleton even further.

Cheers!

    glr2.cc: also run all the calculator tests
    
    This revealed issues with yy_symbol_print and yy_reduce_print.
    
    * tests/calc.at (AT_CHECK_CALC_GLR_CC): Also check glr2.cc.
    * data/skeletons/glr2.cc: Don't pass the user arguments to
    yy_symbol_print and yy_reduce_print, since they have it in the parser
    object.
