Recently, we had a GS offloader alert on chromeos-server118.mtv.
This repair job was failing to offload:
    http://cautotest-prod/tko/retrieve_logs.cgi?job=/results/hosts/chromeos2-row8-rack5-host11/88341-repair/

The reason for the failure was this directory:
    after_sysrq.chromeos2-row8-rack5-host11/log/dptf

The directory mode looks like this:
    d-wxr----x  2 chromeos-test eng   4096 Jan  7 05:17 dptf

This tracks what you find on a typical DUT:
    d-wxr----t. 2 root root 4096 Jan  3 11:12 /var/log/dptf

Because the directory denies read access to the owner, gs_offloader
can't offload the job.

We need to adjust gs_offloader so that this kind of event isn't a
failure.  Most likely, that means we need to go through the results
enforcing the following:
  * For every directory, force "chmod u+rx"
  * For every file, force "chmod u+r"
