Use conditional build for retrieving ccache.
Some krb5 functions needn't be available for retrieving ccache with principal. Therefore ifdef is used to solve this situation with older version of libkrb5. There were two functions with similar functionality in krb5_child and krb5_utils. They were merged to one universal function, which was moved to file src/util/sss_krb5.c
