fix(keyring-eth-ledger-bridge): trim 0x prefix for signTransaction (due to latest @ethereumjs upgrade)

[dawnseeker8]

This PR will fix the ledger sign transaction issue due to this ethereumjs upgrade PR #209

and basically the ethereumjs upgrade code change make the transaction rawTxHex contain 0x prefix which is not valid for to @ledgerhq/hw-eth-app clearSignTransaction function. that functions expect a rawTxHex without 0x prefix.
