[SPARK-4076] Parameter expansion in spark-config is wrong
In sbin/spark-config.sh, parameter expansion is used to extract source root
as follows.
this="${BASH_SOURCE-$0}"
I think, the parameter expansion should be ":" instead of "".
If we use "-" and BASH_SOURCE="", (empty character is set, not unset),
"" (empty character) is set to $this.
