absl: fix potential int overflow in ELF reading
Both e_shentsize and e_shstrndx are uint16, so the product elf_header.e_shentsize * elf_header.e_shstrndx can overflow the promoted type int (MAX_UINT16 * MAX_UINT16 > MAX_INT), which is undefined behavior. Not sure if it can affect any real cases or not, though. Cast e_shentsize to loff_t instead of e_shoff. This makes both multiplication and addition to use loff_t type.
