Subject: Qt4Macros: Don't AUTOMOC or AUTOUIC qt4-generated files

Suppress AUTOMOC and AUTOUIC on files generated by Qt4 wrapping macros;
particularly, those generated by `qt4_wrap_cpp`, `qt4_wrap_ui`, and
`qt4_add_resources`.  None of these should need AUTOMOC or AUTOUIC
treatment, and CMP0071 makes it important to mark this explicitly.
