clean up ubuntu versions

oneiric is long dead, remove references to it whenever possible
(one more subtle issue in cinder should be a seperate patch). This
includes removing the oneiric only tool build_uec.sh.

also remove the bulk of references to quantal, which is 8 months
out of support. note: raring only has support for the rest of the
month.
