Ulrich Drepper c8727fa6e5 Fix Linux getlogin{_r,} implementation 
The old implementation uses fd 0 to determine the login TTY.  This
was needed because using /dev/tty it is not possible to deduce the
login TTY.  For some time now there is the pseudo-file
/proc/self/loginuid which directly helps us to find the user.  Prefer
using this file.  It also works if stdin is closed, redirected, or
re-opened.
