fixed /bin/login

[Stan Johnson]

SGI may have posted the wrong version of the new /bin/login on sgi.com.
We have tested and verified a version which works, which is different
from the sgi.com version.  Ours has 122928 bytes and a checksum of 25777.
The new login on sgi.com has 118832 bytes and a checksum of 57910.  Our
original /bin/login had 118832 bytes and a checksum of 55583.
