Ansible/Warden-Filer-Receiver: fix installation

The main task file now:
 - creates the bin directory (default /opt/warden-filer)
 - copies the binaries properly
 - applies executable permission to the init.d script
 - creates main binary symlink at /usr/local/bin/warden_filer.py
 - creates /etc/default/warden_filer_receiver file in the correct path
