nss_ldap: fixing crash with glibc >= 2.16
I update it to the latest version, 265. Then I use some patches: The nss_ldap-265-glibc-2.16.patch is the one that fixes the crash. The crashes.patch is another one that I took from RH that said to fixes somes crashes, but it didn't fix the crash I was seeing. But I guess it fixes something.
