Common/command: Guard strchr/strlen from NULL pointer
Guard strchr/strlen from being called with NULL pointer.
This line is crashing when command "env" is called without subcommand.
The cmd is NULL in this case because the calling function "do_env"
decremented the argc without checking if there are still arguments available.
