perf tests: Fix record+probe_libc_inet_pton.sh without ping's debuginfo
When we don't have the iputils-debuginfo package installed, i.e. when we don't have the DWARF information needed to resolve ping's samples, we end up failing this 'perf test' entry: # perf test ping 62: probe libc's inet_pton & backtrace it with ping : Ok # rpm -e iputils-debuginfo # perf test ping 62: probe libc's inet_pton & backtrace it with ping : FAILED! # Fix it to accept "[unknown]" where the symbol + offset, when resolved, is expected. I think this will fail in the other arches as well, but since I can't test now, I'm leaving s390x and ppc cases as-is.
