perf test: Fix test case perftool-testsuite_report for s390

Test case perftool-testsuite_report fails on s390 for some time
now.

Root cause is a time out which is too tight for large s390 machines.
The time out value addr2line_timeout_ms is per default set to 1 second.

This is the maximum time the function read_addr2line_record() waits for
a reply from the forked off tool addr2line, which is started as a child
in interactive mode.

It reads stdin (an address in hexadecimal) and replies on stdout with
function name, file name and line number. This might take more than one
second.

However one second is not always enough and the reply from addr2line
tool is not received. Function read_addr2line_record() fails and emits
a warning, which is not expected by the test case. It fails.

Output before:
