[FYI] {master} yacc tests: avoid a spurious failure with Sun C++ 5.9

[Stefano Lattarini]

* t/yacc-cxx.sh (parse1.yy): When calling the 'getchar' function declared
in the #included <cstdio>, fully qualify it as std::getchar', to avoid
Sun C++ 5.9 erroring out with:
"parse1.yy", line 5: Error: The function "getc" must have a prototype.
* t/yacc-clean-cxx.sh (sub1/parsefoo.yxx): Likewise.
