Flush unity output before a potential longjmp

Flush the unity stdout buffer before calling TEST_ABORT().
This is because if TEST_PROTECT() has not previously been called this will cause a segmentation fault and the stdout buffer will fail to print

Although the segmentation fault will still occur, the error that caused it will at least be displayed
