[PATCH] docker: Base Fedora MinGW cross containers on the base Fedora image

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The only difference between fedora-winXX-cross.docker and
fedora.docker is the specific QEMU_CONFIGURE_OPTS environment
variable. All the rest can be inherited from the generic Fedora
image.
Basing the cross containers on the generic Fedora allows us to
- save registry/local storage
- use more tools in the cross container (ccache for example).
