[nifm, bsd] add airplane mode functionality to a new nifm call and fix local files (#225)

There is a cmd `IsAnyInternetRequestAccepted` which is called by games like DOOM to check if internet access is available. Adds the newly added airplane mode there.
Also, moved down the airplane mode check on bsd to also check if it's a local file request, if it is, let it connect. (SMO guide web applet for example)
+ adds a check in IRequest if airplane mode is active, which then results in an not succeeding requests.
