[Buildroot] new package dvbsnoop

[Carsten Schoenert]

Hello,

several times (or more precise years :) ) ago I worked on a digital
settopbox provided by the german PayTV provider Premiere, now known as
Sky. The box is called 'DBox2'.
Some guys ported in the beginning of 2000 Linux into this box, dvbsnoop
was used on this box to be able to look into the digital data of DVB
signals. It's a useful and powerful tool to analyse and or dump
transponder streams, and this also after the main developing times.

Dvbsnoop isn't now really under development, it just works as espected.

Please let me know if something isn't right.

Regards
Carsten
