test-runner: pass kmemleak and kmsg to Cmd.run

test-runner.py orchestrates all of the ZTS executions. The `Cmd` object
manages these process, and its `run` method specifically invokes these
possibly long-running processes, possibly retrying in the event of a
timeout. Since its inception, memory leak detection using the kmemleak
infrastructure [1], and kernel logging [2] have been added to this run
mechanism.

However, the callback to cull a process beyond its timeout threshold,
`kill_cmd`, has evaded modernization by both of these changes. As a
result, this function fails to properly invoke `run`, leading to an
untrapped exception and unreported test failure.

This patch extends `kill_cmd` to receive these kernel devices through
the `options` parameter, and regularizes all the `.run` calls from
`Cmd`, and its subclasses, to accept that parameter.
