Alex Mendoza c9780d9095 [NTOS:OB] Validate ACCESS_SYSTEM_SECURITY in ObpIncrementHandleCount
Validate ACCESS_SYSTEM_SECURITY access requests when creating a new
handle in ObpIncrementHandleCount.

- Check for SeSecurityPrivilege (with SeSinglePrivilegeCheck) when a
  caller requests ACCESS_SYSTEM_SECURITY on handle creation.
- Take away ACCESS_SYSTEM_SECURITY from RemainingDesiredAccess /
  PreviouslyGrantedAccess if the privilege isn't held.
