data: Optimize Data signing

As of this commit, KeyChain::sign pre-allocates EncodingBuffer, requests
unsigned portion of Data using Data::wireEncode(EncodingBuffer, true),
and then appends the resulting signature and prepends Data packet
header.  This way there is no extra memory allocation after Data packet
is signed.
