Docker run_command validation is incorrect, should be list of strings

Line 770 in 739a415

'run_command': (str, False),

Docker run_command should be a list of strings, not a string. See https://www.packer.io/docs/builders/docker.html#run_command

I'll throw a pull request together if I get the time, but wanted to at least document.
