mynewt_smp_svr: Stack is 8 byte aligned, 564 -> 568 #61

On the mynewt side, OS main stack size should be set to 568 since taskstat shows the 8 byte aligned value for the stack size

@vrahane This is OK, but it does not change anything in the results, OS_STACK_ALIGN does add the 4 bytes because the value is not 8-byte aligned.

@utzig Why do you say that ?

@utzig the problem was that the stack size, even though it corrects it, it is still not what we have specified as a syscfg which causes bit of a confusion while looking at the taskstats. Hence, the change.
