efi_loader: correct signature of GetPosition, SetPosition

The UEFI spec requires that file positions are passed as u64 in
GetPosition() and SetPosition().

Check if the file handle points to a directory in GetPosition().

Provide a unit test for GetPosition() and SetPosition().

Fix Coverity warning CID 184079 (CONSTANT_EXPRESSION_RESULT).

Add comments.
