[SPARK-10359][PROJECT-INFRA] Use a more random suffix in
dev/test-dependencies.sh
This patch aims to fix another potential source of flakiness in the
`dev/test-dependencies.sh` script.
@pwendell's original patch and my version used `$(date +%s | tail -c6)` to
generate a suffix to use when installing temporary Spark versions into the
local Maven cache, but this value only changes once per second and thus is
highly collision-prone when concurrent builds launch on AMPLab Jenkins. In
order to reduce the potential for conflicts, this patch updates the script to
call Python's random number generator instead.
