[autotest] network/frame_sender: grab send_management_frame logs

We run send_management_frame as a sort of background process, tracked by
PID. Grab its redirected stdout/stderr after we kill it.

We have to wait for the process to actually die, otherwise we might miss
some of its std{out,err}. I open-coded the simple shell loop, since
utils.poll_for_condition() would require a new host.run() (SSH)
invocation for each 'kill', which would be needlessly slow.

BUG=chromium:511318
TEST=run network_WiFi_ChannelScanDwellTime (also, with modifications to
     run multiple FrameSender), look for debug/frame_sender_*.log
