The current s390 machine uses the virtio console as default console,
but this doesn't mean that we always want to keep it that way for new
machines.
This patch introduces a way for a machine type to specify that it wants
the default console to be an SCLP console, which is a lot closer to what
real hardware does.

Commits fc8c5b8c41 (Makefile.user: Define
CONFIG_USER_ONLY for libuser/) and
dd83b06ae6 (qom: Introduce CPU class)
specifically prepared the qom/cpu.c file to be compiled differently for
softmmu and *-user. This broke as part of build system refactorings
while CPU patches were in flight, adding conditional fields
kvm_fd (8737c51c04) and
kvm_vcpu_dirty (20d695a925) for softmmu.
linux-user and bsd-user would therefore get a CPUState type with
instance_size ~8 bytes longer than expected.
Fix this by unconditionally having the fields in CPUState.
In practice, target-specific CPU types' instance_size would compensate
this, and upstream qom/cpu.c does not yet touch any affected field.
