libpayload: Catch exceptions and print out an error message.
Give some indication what happened instead of just crashing. As part of setup, cause an exception and make sure that we get the right one, and that we recover correctly. Hence we have some assurance that if they really happen we can handle them. Built and booted into test payload on Snow. Saw the built in test function worked correctly. Artificially added code which got an exception and saw that the error information prints correctly.
