[EVM] An error occurs when ecrecover is called.

[toshihiko-okubo]

Describe the Bug
The signature to be passed to btcec.RecoverCompact must have the structure [v, r, s], but the current implementation of ecrecover has the structure [r, s, v], which always causes an error.
https://github.com/btcsuite/btcec/blob/BTCEC_0_2_2/signature.go#L386-L391

To Reproduce
Implement and call the function to call ecrecover in smartContract.

Expected Behavior
https://github.com/hyperledger/burrow/blob/v0.34.4/execution/native/precompiles.go#L75-L82

v := ctx.Input[binary.Word256Bytes : 2*binary.Word256Bytes]
if !binary.IsZeros(v[:len(v)-1]) {
	return nil, fmt.Errorf("ecrecover: recovery ID is larger than one byte")
}
// Copy in v to first element of sig
sig[0] = v[len(v)-1]

// Copy in r, s
copy(sig[1:], ctx.Input[2*binary.Word256Bytes:4*binary.Word256Bytes])
