perf test: Fix exit code for record+probe_libc_inet_pton.sh
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 :
...
