CHROMIUM: mm: lower oom dump burst limit to 1

Dumping tasks during oom seems to cause noticeable UI jank.  The kernel
has a mechanism for disabling the dump altogether, but the dump can
still be useful to see in feedback reports. So, this lowers the
default ratelimit burst from 10 to 1 so that we still get one report
of what was consuming memory when we get OOMs.

BUG=chromium:702707
TEST=induce an OOM and check for UI jank
