builtin/apply: make write_out_results() return -1 on error
To libify `git apply` functionality we have to signal errors to the
caller instead of exit()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", write_out_results() should return -1 instead of
calling exit().
