qemu: Upgrade 9.2.3 -> 10.0.0

In version 10, emulation of 64 bit targets on 32 bit
systems is no longer supported. The target list is tweaked accordingly.

Running qemu on *any* 32 bit host is also deprecated and going to be
removed upstream in a later version soon:

The pixman configuration option now needs to be specified so add a
PACKAGECONFIG entry, defautling to enabled. This is a required dependency
of some of the graphical backends like gtk.
