making usrp2_socket_opener suid root is the best way to set things up.  
This allows us to use the least privileges possible on all other 
programs, and usrp2_socket_opener is a nice short program that can 
easily be audited.

Note that if you do a make install again it may overwrite your 
usrp2_socket_opener, and then it won't have the permissions set 
anymore.  You can get by this by putting the suid copy in your ~/bin 
directory, which won't be overwritten every time.
