src/login.c: Fix checking whether 'login' is started as 'init'

When PAM is not used, login does not fork itself so its own PID should
be checked instead of parent PID.

Fixes: b44a6c316d96ab038492c63443156810670d176d (26-12-2007; "If started as init, login and sulogin need to start a new session.")
