Update TTYd installation

-Now copies passwd from /etc to /opt/etc in the case of SELINUX is enabled on the module
-Sets the root user's home folder to /usrdata/root to allow for default writability and more available space
-Creates a .profile to be placed in the home directory that sets the correct $PATH This file can be used to execute a startup menu later.
-Creates /usrdata/root/bin for binaries to be pushed to later. This is added to the $PATH as well by .profile
