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