tools lib traceeveent: Allow for negative numbers in print format

It was reported that "%-8s" does not parse well when used in the printk
format. The '-' is what is throwing it off. Allow that to be included.

Reporter note:

Example before:

  transhuge-stres-10730 [004]  5897.713989: mm_compaction_finished: node=0
  zone=>-<8s order=-2119871790 ret=

Example after:

  transhuge-stres-4235  [000]   453.149280: mm_compaction_finished: node=0
  zone=ffffffff81815d7a order=9 ret=

(I will send patches to fix the string handling in the tracepoints so
it's on par with in-kernel printing via trace_pipe:)

  transhuge-stres-10921 [007] ...1  6307.140205: mm_compaction_finished: node=0
  zone=Normal   order=9 ret=partial
