tools lib traceevent: Fix memory leak in pretty_print()
commit de04f8657de9d3351a2d5880f1f7080b23b798cf upstream. Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.
