[PATCH v2 18/30] accel/kvm: move KVM_HAVE_MCE_INJECTION define to kvm-all.c

[Pierrick Bouvier <pierrick.bouvier@linaro.org>]

This define is used only in accel/kvm/kvm-all.c, so we push directly the
definition there. Add more visibility to kvm_arch_on_sigbus_vcpu() to
allow removing this define from any header.

The architectures defining KVM_HAVE_MCE_INJECTION are i386, x86_64 and
aarch64.
