packagegroup-self-hosted: move graphics packages to graphics group

The following packages are gui based tools:
  xdg-utils       # A set of common interfaces for desktop
  leafpad         # A GTK+ text editor used in Build Appliance
  midori          # A web browser used in Build Appliance
  pcmanfm         # PCManFm file manager used in Build Appliance
  vte             # Virtual terminal emulator GTK+ widget library

Move them to packagegroup-self-hosted-graphics so that we can make
a graphics free self-hosted image by excluding the
packagegroup-self-hosted-graphics.
