Is this file supposed to only be built on Mac? Name these files
binary_integrity_incident_mac.* (and name the class similarly to avoid
confusion). That way, they’ll automatically be built on Mac but not on other
platforms. See build/filename_rules.gypi.

But as grt suggested, it seems that this isn’t strictly needed, and this can
just use BinaryIntegrityIncident.
