This flag allows systems that are running runc to allocate tty's that
they own and provide to the container.

When we are using user namespaces we need to make sure that when we do
not have a TTY we change the ownership of the pipe()'s used for the
process to the root user within the container so that when you call
open() on any of the /proc/self/fd/*'s you do not get an EPERM.

When we use ```cat | runc``` or ```runc /dev/stdin < config.json```,
it will fail and output ```FATA[0000] Container start failed: inappropriate ioctl for device```.
It is hard for the users to find out the reason from the message:
the config.json enables the terminal but the user redirect the stdin
to an non-terminal file.
After this patch, the output will be
```FATA[0000] Container start failed: Failed to set the terminal from the stdin: inappropriate ioctl for device```
So the user can disable the terminal in the config.json.

Should compile now without errors but changes needed to be added for each system so it actually works.
main_unsupported.go is a new file with all the unsupported commands
