exec: Don't abort when we can't allocate guest memory
We abort() on memory allocation failure. abort() is appropriate for
programming errors. Maybe most memory allocation failures are
programming errors, maybe not. But guest memory allocation failure
isn't, and aborting when the user asks for more memory than we can
provide is not nice. exit(1) instead, and do it in just one place, so
the error message is consistent.
