dtrace: Allow for reproducible .o file builds.

* dtrace.in: When building packages like libvirt on openSUSE that
  link a libvirt_probes.o from dtrace, the build results differed
  across builds. This is because the source's temporary filename
  was in the .o. Make the temporary filename reproducible.
