Remove genericity, x64 and renamed stuff

As per discussion on the github issue, the following changes were made:

* Project renamed from elevate to kitrap0d, implying that this is not
  intended to be a generic local priv esc exploit container.
* Container DLL no longer generic, always calls the kitrap0d exploit.
* Removal of all x64 code and project configurations.
* Invocation of the exploit changed so that the address of the payload
  is passed in to the exploit entry point. The exploit is now responsible
  for executing the payload if the exploit is successful. This removes
  the possibility of the payload getting executed when the exploit fails.
* Source moved to the appropriate CVE folder.
* Binary moved to the appropriate CVE folder.
* Little bit of source rejigging to tidy things up.
