index-pack: correct "offset" type in unpack_entry_data()

unpack_entry_data() receives an off_t value from unpack_raw_entry(),
which could be larger than unsigned long on 32-bit systems with large
file support. Correct the type so truncation does not happen. This
only affects bad object reporting though.
