Sandipan Das 3eae52f842 perf tests: Fix record+probe_libc_inet_pton.sh for powerpc64
For powerpc64, this test currently fails due to a mismatch in the
expected output.

This can be observed on a powerpc64le system running Fedora 27 as shown
below.

  # perf test -v "probe libc's inet_pton & backtrace it with ping"
