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", die_on_unsafe_path() should return a negative integer instead of calling die(), so while doing that let's change its name to check_unsafe_path().
