[Libguestfs] [PATCH 2/2] p2v: use standard license type in about dialog

[Pino Toscano]

GtkAboutDialog in GTK+ 3 can be configured with few standard licenses,
including GPL2+.  Thus, just set that property, so the about dialog will
show its own license text, and there is no need for our custom one.
