tools: fix check repositories script for macs (envoyproxy#4914)

Fix check_repositories script when running on a mac. The version of grep that comes as part of OSX does not support the -P flag. This will instead utilize git grep to pattern match. Risk Level: Low Testing: Manually ran the script on my machine. See attached output below. Docs Changes: N/A Release Notes: N/A Signed-off-by: Derek Schaller <[email protected]>
