[ion] 17231: - Implement KeQueryBasePriorityThread to return the actual Base Priority Increment (or Saturation Increment) to NtQueryInformationThread. The value win32 works with is actually (usually) the difference between process and thread Base Priorities.

- Implement KeQueryBasePriorityThread to return the actual Base Priority
Increment (or Saturation Increment) to NtQueryInformationThread. The
value win32 works with is actually (usually) the difference between
process and thread Base Priorities.
This fixes another WINE test.
