[PATCH] files-hosts fix for to small buffer

[Thorsten Kukuk]

Hi,

If you have one alias for a lot of entries in /etc/hosts or very 
long lines, the current glibc version will fail. Reason: files-hosts.
from libnss_files runs out of buffer space, but does not set all
variables, so it will never be called with a bigger buffer. Appended
patch fixes this problem.
