run_cmd() and friends: Make args a list[str]

This is a code maintenance commit: some run_xxx() helper functions
take a string, some a list, and some just digest all arguments and
pass them on as a list to exec() to be executed. That's highly
inconsistent. This commit changes that to list-only.

Except for the run_cmd() method of SSHClient, which is still run as a
shell method, because, erm, it's a shell. Might be changed in the
future for consistency reasons.
