perf test record+probe_libc_inet_pton: Fix call chain match on x86_64

The test case probe libc's inet_pton & backtrace it with ping fails with
Fedora 38 on x86_64.

Function getaddrinfo() does not show up in the call chain anymore:

  # ./perf script
  ping  1803 [000] 728.567146: probe_libc:inet_pton: (7f5275afc840)
            133840 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6)
             27b4a __libc_start_call_main+0x7a (/usr/lib64/libc.so.6)
             27c0b __libc_start_main@@GLIBC_2.34+0x8b (/usr/lib64/libc.so.6)

  ping  1803 [000]   728.567184: probe_libc:inet_pton: (7f5275afc840)
            133840 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6)
              493e main+0xcde (/usr/bin/ping)
             27b4a __libc_start_call_main+0x7a (/usr/lib64/libc.so.6)

  #

which causes the test case to fail. Remove function getaddrinfo()
from list of expected functions.

Output before:

  # ./perf test 'libc'
  91: probe libc's inet_pton & backtrace it with ping    : FAILED!
  #

Output after:

  # ./perf test 'libc'
  91: probe libc's inet_pton & backtrace it with ping    : Ok
