Subject: [PATCH] perf tools: Use "grep -F" instead of "fgrep"

There exists the following warning when execute perf test
record+probe_libc_inet_pton.sh:

fgrep: warning: fgrep is obsolescent; using grep -F

This is tested on Fedora 38, the version of grep is 3.8,
the latest version of grep claims the fgrep is obsolete,
use "grep -F" instead of "fgrep" to silence the warning.
