login: update UTMP before forking
/bin/login updates the preliminary UTMP record created by /bin/getty for
$LOGNAME. However, if the PID of login is not the same as getty, then
it will create a new entry. This causes GLIBC getlogin(3) to return the
string 'LOGIN' (set by getty) instead of $LOGNAME. This affects tools
like /usr/bin/logname but also various 3rd party PAM applications.
