    perf test record_probe_libc_inet_pton: Fix test on s/390 where 'text_to_binary_address' now appears on the backtrace
    
    perf test '84: probe libc's inet_pton & backtrace it with ping' fails on
    s390. Debugging revealed a changed stack trace for the ping command
    using probes:
    
      ping 35729 [002]  8006.365063: probe_libc:inet_pton: (3ff9603e7c0)
                        13e7c0 __GI___inet_pton+0x0 (/usr/lib64/libc.so.6)
                --->    104371 text_to_binary_address+0xef1 (inlined)
                        104371 gaih_inet+0xef1 (inlined)
                        104371 __GI_getaddrinfo+0xef1 (inlined)
                          5d4b main+0x139b (/usr/bin/ping)
    
    The line "---> text_to_binary_address ..." is new. It was introduced
    with glibc version 2.36.7.2 released with Fedora 37 for s390.
    
    Output before
    
      # perf test inet_pton
      84: probe libc's inet_pton & backtrace it with ping   : FAILED!
      #
    
    Output after:
    
      # perf test inet_pton
      84: probe libc's inet_pton & backtrace it with ping   : Ok
