setuid: Create token from scratch without credentials of caller

Browse Source 
* sec_auth.cc (get_token_group_sidlist): Drop auth_luid and
	auth_pos parameter.  Remove code adding a logon SID.
	(get_initgroups_sidlist): Drop auth_luid and auth_pos parameter.
	Drop in call to get_token_group_sidlist. Accommodate in callers.
	(get_setgroups_sidlist): Ditto.
	(create_token): Explicitely set auth_luid to ANONYMOUS_LOGON_LUID
	or LOCALSERVICE_LUID depending on OS.  Explain why.
	Remove handling of logon SID since we don't generate one anymore.
	(lsaauth): Drop now unused local variable auth_luid and auth_pos.
	* wincap.h (wincaps::has_broken_whoami): New element.
	* wincap.cc: Implement above element throughout.
