pack-objects: pass length to check_pack_crc() without truncation
On 32 bit systems with large file support, unsigned long is 32-bit
while the two offsets in the subtraction expression (pack-objects has
the exact same expression as in sha1_file.c but not shown in diff) are
in 64-bit. If an in-pack object is larger than 2^32 len/datalen is
truncated and we get a misleading "error: bad packed object CRC for
..." as a result.
Use off_t for len and datalen. check_pack_crc() already accepts this
argument as off_t and can deal with 4+ GB.
