Create temporary files in the system's temp directory.

In Brillo, the temporary directory might not be /tmp. This patch uses
base::GetTempDir() instead and removes the hard-coded mentions of /tmp
when creating temporary directories.

Bug: 22024447
Test: `update_engine_client --update --omaha_url=...` mounts /system on the temp directory under /data/local/tmp
