vl: Report accelerator not supported for target more nicely

When you ask for an accelerator not supported for your target, you get
a bogus "accelerator does not exist" message:

  $ qemu-system-arm -machine none,accel=kvm
  KVM not supported for this target
  "kvm" accelerator does not exist.
  No accelerator found!

Suppress it.
