use child_process member "args" instead of string array variable

Browse Source 
Use run_command() with a struct child_process variable and populate its
"args" member directly instead of building a string array and passing it
to run_command_v_opt().  This avoids the use of magic index numbers and
makes simplifies the possible addition of more arguments in the future.
