This fixes record+probe_libc_inet_pton.sh from always exiting with code
0 and making the test pass even if the perf script output does not match
the expected pattern.
The issue can be observed if this test is run with the verbose flags as
shown below:
60: probe libc's inet_pton & backtrace it with ping :

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
