perf test: Fix test case inet_pton to accept inlines. 

[ Upstream commit 0f19a038af ]

Using Fedora 27 and latest Linux kernel the test case
trace+probe_libc_inet_pton.sh fails again on s390.  This time is the
inlining of functions which does not match.  After an update of the
glibc (from 2.26-16 to 2.26-24) the output is different

The expected output is:

             __inet_pton (/usr/lib64/libc-2.26.so)
             gaih_inet (inlined)
             ....

The actual output is:

  1 packets transmitted, 1 received, 0% packet loss, time 0ms
  rtt min/avg/max/mdev = 0.061/0.061/0.061/0.000 ms
       0.000 probe_libc:inet_pton:(3ffb2140448))
             __inet_pton (inlined)
             gaih_inet.constprop.7 (/usr/lib64/libc-2.26.so)
             ...

Fix this by being less strict on 'inlined' verses library name and
accept both
