"debugd" crash dumps accumulating

Reported by jrbarnette@chromium.org, Jun 5 2018

Issue description

Browsing through logs, I'm seeing that DUTs in the Autotest Lab
accumulate a lot of crash dumps with the name "debugd" embedded
in them.  To see it, I'm running commands like this:

$ dut-status -f -b elm -p bvt -d 8 | grep provision | sed 's=.*\(results/.*\)=gsutil cat gs://chromeos-autotest-\1*/status.log=' | sh | grep crashdump

That produces lots of lines like this:
INFO	----	----	timestamp=1528208125	localtime=Jun 05 07:15:25	Host crashdump exists: /var/spool/crash/debugd.20180605.071352.2165.meta

The problem is widespread, but not universal.  I've seen "debugd"
dumps on caroline, peach_pit, and kevin, but not nyan_big or elm.

Of course, that means to see the problem, you'll need a command more
like this one:
$ dut-status -f -b peach_pit -p bvt -d 8 | grep provision | sed 's=.*\(results/.*\)=gsutil cat gs://chromeos-autotest-\1*/status.log=' | sh | grep crashdump
