seq66: enable Qt wrapper to fix plugin loading

Without the change `qseq66` fails to load as:

    $ qseq66
    qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
    This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

While at it added `mainProgram`.
