tsocks: Add tsocks to meta-network/recipes-protocols

The tsocks program is frequently used to easily wrap any generic
program such as telnet, ssh, wget or any other tcp socket program
using an LD_PRELOAD library.  One might use an ssh tunnel and wget for
example.

Example of tunnel via ssh to remote url:

ssh -N -D 1080 $REMOTE_HOST_TUNNEL_ENDPOINT &

cat<<EOF>tsocks.conf
server_port = 1080
server = 127.0.0.1
EOF

TSOCKS_CONF_FILE=$PWD/tsocks.conf tsocks curl $REMOTE_URL
