Q*ApplicationPrivate: remove unused "flags" arguments

They weren't flags. They were the version of Qt that was used in
compiling the application itself. The protection against rollback isn't
necessary any more, since qversiontagging.h, which applies to everything
and not just the main application binary. And using them to make
decisions on functionality or behavior is misguided (see previous
commit).

This commit does not deprecate the front-end classes' argument. In the
future, we may find some need for them.
