perf auxtrace: Fix itrace defaults for perf script

Commit 4eb068157121 ("perf script: Make itrace script default to all
calls") does not work for the case when '--itrace' only is used, because
default_no_sample is not being passed.

Example:

 Before:

  $ perf record -e intel_pt/cyc/u ls
  $ perf script --itrace > cmp1.txt
  $ perf script --itrace=cepwx > cmp2.txt
  $ diff -sq cmp1.txt cmp2.txt
  Files cmp1.txt and cmp2.txt differ

 After:

  $ perf script --itrace > cmp1.txt
  $ perf script --itrace=cepwx > cmp2.txt
  $ diff -sq cmp1.txt cmp2.txt
  Files cmp1.txt and cmp2.txt are identical
