crash-reporter: Re-enable CollectBadDirectory unittest

The KernelCollectorTest.CollectBadDirectory unittest was first re-enabled by
sergiu@ in https://gerrit.chromium.org/gerrit/5433, but it broke the
buildbots and had to be re-disabled.  So I'm trying again, but this time I
have the power of trybots!  I also added code to output the log if it fails
again.

BUG=chromium-os:18622
TEST=Ran unittests.  Ran trybots on: alex-paladin, amd64-generic-paladin,
arm-tegra2-paladin, lumpy-paladin, stumpy-paladin.
