Regenerate qconf.moc when the moc command is changed.

This also allows 'make mrproper' to clean it up. Previously, it was
not cleaned up because 'clean-files += qconf.moc' was missing.
Now 'make mrproper' correctly cleans it up because files listed in
'targets' are cleaned.

Changes in v2:
  - Use 'targets' instead of 'clean-files'
