Create missing SSSD_PUBCONF_KRB5_INCLUDE_D_DIR
One some distributions, namely Suse, the SSSD_PUBCONF_KRB5_INCLUDE_D_DIR
does not exist by default. Ipa-client-install will fail to initialize
the kerberos ticket and error when this directory does not exist.
This patch simply creates the directory if it does not exist before
adding the include statement into /etc/krb5.conf
