[COMMITTERS] pgsql: Fix and simplify check for whether we're running as Windowsserv

Fix and simplify check for whether we're running as Windows service. If the process token contains SECURITY_SERVICE_RID, but it has been disabled by the SE_GROUP_USE_FOR_DENY_ONLY attribute, win32_is_service() would incorrectly report that we're running as a service. That situation arises, e.g. if postmaster is launched with a restricted security token, with the "Log in as Service" privilege explicitly removed. Replace the broken code with CheckProcessTokenMembership(), which does this correctly. Also replace similar code in win32_is_admin(), even though it got this right, for simplicity and consistency. Per bug #13755, reported by Breen Hagan. Back-patch to all supported versions. Patch by Takayuki Tsunakawa, reviewed by Michael Paquier.
