TESTS/TIER: bug-1303028-Rebalance-glusterd-rpc-connection-issue.t

PROBLEM: spurious failure of the test.

CAUSE: the function "rebalance_run_time" calculates the total time
the tier has been running for. this being a test case, the run time
of tier can be 0 and when the function adds up zero it results in
zero. and thus it starts to fail.

FIX: Give it some time for the function to add up the values.
