Redundant storage of VhdlParser_adj.cc, it can be regenerated

The file `VhdlParser_adj.cc` is independent of the javacc program, it is just dependent on `VhdlParser.cc` (and `vhdl_adj.py`) and therefore can be regenerated at any time.
It is better to regenerate it (and store it) into `generated_src ` in stead of in the repository.
