Use the latest hwpacks available under http://snapshots.linaro.org/oneiric/

[Deepti B. Kalakeri]

The hwpacks under http://snapshots.linaro.org/11.05-daily/linaro-hwpacks/ seems to deleted.
Hence the builds referring to the above are failing with the following error:

+ python lci-build-tools/get_latest_slo_hwpack
Traceback (most recent call last):
 File "lci-build-tools/get_latest_slo_hwpack", line 11, in <module>
   hwpack_id, hwpack_url = find_latest_hwpack(hwpacktype)
 File "<https://ci.linaro.org/jenkins/job/linux-linaro-3.1_beagle-omap2plus/ws/lci-build-tools/find_latest.py",> line 102, in find_latest_hwpack
   build_id, filename = find_latest(url, hwpackextra)

   tgz_url = os.path.join(latesturl, filename)

   if b.startswith('/'):
AttributeError: 'NoneType' object has no attribute 'startswith'

Hence, move to using hwpacks under http://snapshots.linaro.org/oneiric/.
