[SPARK-23295][Build][Minor]Exclude Waring message when generating versions in make-distribution.sh

[yaooqinn]

What changes were proposed in this pull request?

When we specified a wrong profile to make a spark distribution, such as -Phadoop1000, we will get an odd package named like spark-[WARNING] The requested profile "hadoop1000" could not be activated because it does not exist.-bin-hadoop-2.7.tgz, which actually should be "spark-$VERSION-bin-$NAME.tgz"

How was this patch tested?

before

build/mvn help:evaluate -Dexpression=scala.binary.version -Phadoop1000 2>/dev/null | grep -v "INFO" | tail -n 1
