win: Fix use of THREAD_ALL_ACCESS on XP

Browse Source 
OpenThread(THREAD_ALL_ACCESS, ...) fails on XP with the uplevel value of
THREAD_ALL_ACCESS, so use the XP value.

Similar to the PROCESS_ALL_ACCESS in
https://codereview.chromium.org/1337133002/ but I mistakenly only
grepped for PROCESS_ALL_ACCESS at that point.
