Jeff King e1d825ad21 diff: modify output_prefix function pointer ...

The uses of the output_prefix function pointer in the diff_options
struct is currently difficult to work with by returning a pointer to a
strbuf. There is only one use that cares about the length of the string,
which appears to be the only justification of the return type.

We already noticed confusing memory issues around this return type, so
use a const char * return type to make it clear that the caller does not
own this string buffer.
