tcsh-6.15.00-closem.patch removed

This patch was never accepted by upstream since upstream does not like
  the solution: http://mx.gw.com/pipermail/tcsh-bugs/2016-April/001031.html

  The issue solved by this patch has been tested on Fedora 23, but
  reproduction was not successful. The package 'nss_ldap' is now obsolote
  (has been retired) and is no longer part of Fedora. It was superseded by
  'nss-pam-ldapd' and 'sssd'. The issue has been most likely mitigated
  with the new identity management used in Fedora (FreeIPA/SSSD).

  In case the issue will re-appear, we will need to find work with
  upstream to find a solution which they would be willing to accept.
