lcg-vomscerts updated

lcg-vomscerts rpm needs to be updated to version 4.5.0-1.
The configuration needs to be changed on the UIs. YAIM site-info.def is not correct. Easiest recipe to change it (from Santanu on TB-SUPPORT) is

sed -c 's/C=CH\/O=CERN\/OU=GRID\/CN=host\//DC=ch\/DC=cern\/OU=computers\/CN=/g ' -i .old site-info.def

and then run the yaim function config_vomses
