perf auxtrace: Fix itrace defaults for perf script
commit 355200e0f6a9ce14771625014aa469f5ecbd8977 upstream.
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
