qemu: fix QEMU_CAPS_NO_ACPI detection

Browse Source 
In commit c4bbaaf8, caps->arch was checked uninitialized, rendering the
whole check useless.

This patch moves the conditional setting of QEMU_CAPS_NO_ACPI to
qemuCapsInitQMP, and removes the no longer needed exception for S390.

It also clears the flag for all non-x86 archs instead of just S390 in
qemuCapsInitHelp.
