NT systems, read primary group SID from process token. Use that info
to create correct group entry. On error or on 9x systems fallback
to emulating Administrators group as before.
(read_etc_passwd): When emulating nonexisting passwd file on NT systems,
read user and primary group SID from process token. Use that info to

build_fhandler.

(fhandler_base::raw_read): Report EISDIR when ERROR_INVALID_FUNCTION or
ERROR_INVALID_PARAMETER and reading a directory.
