container: make sure $HOME is always set

Browse Source 
If the HOME environment variable is not set, make sure it is set to
the configuration found in the container /etc/passwd file.

It was previously depending on a runc behavior that always set HOME
when it is not set.  The OCI runtime specifications do not require
HOME to be set so move the logic to libpod.
