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. Signed-off-by: Thomas Weber <weber@corscience.de>
