[PATCH] login.c argp fix

Hi,

now that argp in glibc is fixed (thanks to the fab 3 and a half
[Roland, Uli, Paul, and me]), we can now remove the ugly kludge in
login.c, see patch below.

Mmh, we should probably make a configure check.  Or do we just assume
people will always use the latest glibc?  I think this came up before,
but with no decision, if we check for a fixed minimal version or do
feature checks.  Roland, what do you think?  It would be easy to test
for _argp_lock_xxx here, which would be a good indication for a safe
argp.

Marco also made a nice argp patch for the console to use it for the
plugins.

Thanks,
Marcus
