Thomas Richter 311693ce81 perf test record+probe_libc_inet_pton: Fix call chain match on s390
With Fedora 38 the perf test 86 probe libc's inet_pton fails on s390.
The call chain of the ping command changed.  The functions
text_to_binary_address() and gaih_inet() do not show up in the call
chain anymore.

Output before:

  # ./perf test -v 86
