Serialize the creation of the dice test's slices.

Browse Source 
Without this, mmake -jN may try to create the slices in parallel. Since that
task involves moving trace counts files, whose names are unpredictable (they
include the process id), we do it by moving all files whose names fit the
associated a pattern. If more than one slice is being created at any one time,
this meant that one invocation of the mmake rule doing the moving can "steal"
the trace counts file from another.
