  printf: fake type node is only needed for aggregation printing

Regular printf validation was passing DTRACEACT_AGGREGATION as kind
argument, even though the action was not doing anything with
aggregations.  Pass DTRACEACT_NONE instead because the argument is not
used in that case.

Also, do not populate the fake type node if the validation is called
for anything other than aggregations.

  alloca: fix subtraction of two alloca pointers

The subtraction of two alloca pointers should not be receiving the
ALLOCA taint because it is an integer value (of type ptrdiff_t).

  trace: print alloca pointers as actual pointer values

Because alloca pointers are stored internally as offsets into the
scratchmem area, they were printed as small integers.  They are
now printed as actual pointer values into kernel space.
