builtin/apply: make find_header() return -128 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, let's make find_header() return -128 instead of
calling die().
We could make it return -1, unfortunately find_header() already
returns -1 when no header is found.
