[BuildRules] Do not set multi-arch env if not enabled

[smuzaffar]

Setting CMSSW env for multi-target first and then setting env for non-multi-target cmssw release causes scram to set wrong LD_LIBRARY_PATH. New cmssw-config tag makes sure to ignore SCRAM_TARGET env ( which could be set by multi-trget release) for a non-multi-target release
