Fix wrong suffix .abis -> .abi

[0xAWM]

1. In some cases, the generated solution cannot be replayed, specifically manifested as "when arg len ==0, arg_offset sometimes exceeds the memory size".

   Lines 95 to 99 in 6378a47

   	let arg = if arg_len == 0 {
   	vec![]
   	} else {
   	interp.memory.get_slice(arg_offset, arg_len).to_vec()
   	};

2. The file suffix generated by solc is abi instead of abis
