Also substitute $HOME in runlabel with user's homedir 

Some programs have their configuration files relative to the user's
home. It would be convenient being able to mount these into the container, but
that requires expansion of `~` or `$HOME` in a label. This commit adds support
for that for the `runlabel` command.
