scripts/tracetool: Use void pointer for vcpu

Browse Source 
dtrace on macOS complains that CPUState * is used for a few probes:

  dtrace: failed to compile script trace-dtrace-root.dtrace: line 130: syntax error near "CPUState"

A comment in scripts/tracetool/__init__.py mentions that:

  We only want to allow standard C types or fixed sized
  integer types. We don't want QEMU specific types
  as we can't assume trace backends can resolve all the
  typedefs

Fixes: 3d211d9f4dbee ("trace: Add 'vcpu' event property to trace guest vCPU")
