ntopng: yosemite fix

Closes #33677.
This is *technically* incorrect. Theoretically, It doesn't need libsodium per se, It needs zeromq to be built with libsodium, but if zeromq isn't built with libsodium I think this *might* help find it. Ideally, this would be changed to something like ``` depends_on "zeromq" => [with-libsodium] => :build ``` but that did not work locally.
