Moving ipaCert from HTTPD_ALIAS_DIR
The "ipaCert" nicknamed certificate is not required to be
in /var/lib/ipa/radb NSSDB anymore as we were keeping a copy
of this file in a separate file anyway. Remove it from there
and track only the file. Remove the IPA_RADB_DIR as well as
it is not required anymore.
