Fix msp430_GCC demo application (#1153)

* Update kernel

Update kernel to bring in a fix for MSP430 task initialization.

* msp430_GCC: Decrease heap size to avoid stack overflow

With 1800 bytes allocated to the heap, the stack overflows while
initializing tasks. Decrease the heap size so we have a bit more space
for the initial stack. We are using most of the heap, so 100 bytes is
about as much as we can decrease it by.
