[autotest] Change resultdir name inside container to be the same as outside container.

The job folder (resultdir) in drone has the format of job_id-user_name.
However, if a test runs inside the container (using server-side
packaging), its folder name is job_id only. The reason was that we
don't want to pass another piece of information to container.

This causes a problem in crash collection. During log collection, test
job creates a file uncollected_log_file to store the list of files to
collect, in the format of source and target pair, where source is the
origin path of the file, e.g., path to a log file in DUT, and target is
a path to the destination to copy to, e.g.,
/usr/local/autotest/results/226/hardware_StorageQualBase.before

If the log collection was interrupted or autoserv process died before
logs can be collected, another autoserv process will be kicked off by
scheduler to run with --collect-crashinfo. The new autoserv process will
read the content of uncollected_log_file and tries to copy file based on
the source/target pair.

Due to the difference of job folder used in container, crash collection
will fail as the target directory does not exist on the drone (as the
job folder only has job_id, but not in the format of job_id-user_name.

This change passes the full job folder name to setup_test call when
setting up the container to run the test. That way, the result path will
be exactly the same inside and outside of the container.
