mesa/arbprog: fix compile errors

When DEBUG_FP is set I see the following compiler errors:

../../src/gitlab_mesa/src/mesa/program/arbprogparse.c: In function '_mesa_parse_arb_fragment_program':
../../src/gitlab_mesa/src/mesa/program/arbprogparse.c:133:4: error: implicit declaration of function '_mesa_print_program'; did you mean '_mesa_parse_arb_program'? [-Werror=implicit-function-declaration]
  133 |    _mesa_print_program(&program->Base);
      |    ^~~~~~~~~~~~~~~~~~~
      |    _mesa_parse_arb_program
../../src/gitlab_mesa/src/mesa/program/arbprogparse.c:133:32: error: 'struct gl_program' has no member named 'Base'
  133 |    _mesa_print_program(&program->Base);
      |                                ^~
