Joel E. Denny 6a358c4b85 [lit] Diagnose insufficient args to internal env
Without this patch, failing to provide a subcommand to lit's internal
`env` results in either a python `IndexError` or an attempt to execute
the final `env` argument, such as `FOO=1`, as a command.  This patch
diagnoses those cases with a more helpful message.
