Steven Rostedt (VMware) b11fb73743 tracing: Fixup trace file header alignment 
The addition of TGID to the tracing header added a check to see if TGID
shoudl be displayed or not, and updated the header accordingly.
Unfortunately, it broke the default header.

Also add constant strings to use for spacing. This does remove the
visibility of the header a bit, but cuts it down from the extended lines
much greater than 80 characters.

Before this change:

 #                           / _----=> need-resched
 #                          | / _---=> hardirq/softirq
