Unify qvm-{copy,move}-to-vm.{gnome,kde} and fix some bugs
- Symlink the other three tools to qvm-copy-to-vm.gnome, use the same
  code where possible, and select differing behavior based on invoked
  name (like the CLI tools). This brings qvm-move-to-vm.kde up to date
  for R4.0 (bugfix on 89183e9).

- Get rid of a window focus race between zenity/kdialog and the
  qubes.Filecopy dom0 permission dialog: Only launch the GUI after the
  first line has been read from qfile-agent.

- Avoid visual glitches (e.g. for a non-existing file) by special-casing
  a no-op progress function for $SIZE == 0.

- Pass -- separator between 'rm -rf' and the files to be removed, in
  case someone or something ever invokes the tool on relative file names
  starting with a dash.

- Pass -b (implies --apparent-size) and -s to du, to simplify percentage
  calculation and to avoid unnecessary output.
