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.
