[PATCH] perf script/intel-pt: set synth_opts.callchain for use_browser > 0

[Song Liu]

Currently, intel_pt_process_auxtrace_info() sets synth_opts.callchain for
use_browser != -1, which is not accurate after we set use_browser to 0 in
cmd_script(). As a result, the following commands sees a lot more errors
like:

  perf record -e intel_pt//u -C 10 -- sleep 3
  perf script

  ...
  instruction trace error type 1 time ...
  ...

This patch fixes this by checking use_browser > 0 instead.
