Without this, multiple runc containers can accidentally share the same cgroup(s)
(and change each other's limits), when runc is invoked from the same directory
(i.e.: same cwd on multiple runc executions).
After these changes, each runc container will run on its own cgroup(s). Before,
the only workaround was to invoke runc from an unique (temporary?) cwd for each
container.
Common cgroup configuration (and hierarchical limits) can be set by having
multiple runc containers share the same cgroup parent, which is the cgroup of
the process executing runc.

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

This removes the Processes slice and only allows for one process of the
container. It also renames TTY to Terminal for a cross platform
meaning.

A couple minor changes to error handling in startup:
1. Don't dump full help/usage text when the only problem is `runc` wasn't started under
root privileges
2. Check for rootfs and make error clear to user when it doesn't exist
3. Change fatal to logrus.Fatal to get nicer output with simple error
message
