[OE-core] [PATCH] Supply correct argument to .deb pre/postinsts

[Linus Wallgren]

The debian policy manual and MaintainerScripts wiki page states that the
postinst script is supposed to be called with the `configure` argument
at first install, likewise the preinst script is supposed to be called
with the `install` argument on first install.
