macOS CIS: Use find command (exposed as fleetd table) instead of relying on the osquery core file table (#12560)

#10292, #12554

When scanning tens of thousands of files for permissions, using the
`find` command exposed as a fleetd table is more performant than trying
to use the `file` table. This change caused the watchdog to *stop*
killing osquery because of exceeding memory or CPU limit.
