Summary [Cocoa] Remove access to the unused 'nvram' system command

Deny access to 'nvram' in the WebKit sandboxes. No API surface interacts with this low-level feature, and other system sandboxes already deny it. It should not have been possible to reach nvram, but there's no reason to allow the sandbox to access it. <rdar://problem/66583129>

Confirmed proper function on iOS device and macOS. Waiting for EWS to show any other impact on downlevel platforms.
