whitelisting additional SentinelOne dylib pattern

[lbergelson]

It seems like SentinelOne is now using dylibs that include a number, possibly randomized in some way.
This causes brew doctor to give a warning, but it should probably be ignored like the previous versions of the sentinel dylib. (It was originally whitelisted here #1440)

updating diagnostic.rb to include a new pattern to ignore dylibs of the form sentinel-*.dylib
