Removed GetThreadId and replaced with optional CLIENTID argument

[wolfcod]

As reported in the pull request #712 GetThreadId api, used in create_remote_thread function is available only from Windows Vista or Windows Server 2003.
The API function is available in platform sdk, but it doesn't reflect Windows XP SP3.

GetThreadId needs an HANDLE to retrieve the UniqueThread value, and the same information is available calling RtlCreateUserThread with the optional argument CLIENTID.

Looks good.
