Currently it is impossible to create an instance of `ELFObjectFile` when the
`SHT_SYMTAB_SHNDX` can't be read. It happens because `ELFObjectFile` tries to
read its entries too early, in the constructor.

This change delays reading of the `SHT_SYMTAB_SHNDX` section entries,
with it llvm-readobj is now able to work with such inputs.
