Bug in RPC capture server

[antonioCoco]

The RPC capture server in charge to grab the ntlmv2 response is using the hardcoded value 268 to hold the data. While there are no particular bugs found on the tested windows, it could have some bugs for win11 and server 2022. The allocation should be dynamically managed with a malloc() call instead of using a local array with fixed size --> https://github.com/antonioCoco/RemotePotato0/blob/main/RPCCaptureServer.cpp#L168
