Remove directory rabbit-hole from generate_logs output

This patch changes the output tarball from generate_logs to directly
include the diagnostic_logs payload directory, instead of the absolute
path chain through /home/chronos/user/Downloads, which will make the
file easier to handle.

It also changes the compression algorithm to gzip, which reduces the
script's runtime on my log-burdened Link by roughly a factor of 4,
while less than doubling the output size (as the time to copy it over
100baseT is negligible compared to the runtime, I would consider this
an improvement).

Add autotest option to generate_logs and fix pstore retrieval

This patch adds the local autotest results directory to the tarball
from generate_logs. This will be helpful in cases where a lab device
looses its connection during a test and autotest's usual log retrieval
mechanism fails.

This also fixes a typo in /dev/pstore/console-ramoops, which prevented
the file from being properly retrieved.

BUG=chromium-os:38995
TEST=Run it with --autotest, make sure the tarball contains
