cccs: add CCCS_CONF_PATH variable to define custom cccs configuration file

If 'CCCS_CONF_PATH' is defined, the specified file is installed as CCCS
configuration file without any modification.
It it is not defined or it is empty, the configuration file in cc_dey
('cc_dey/cccs-daemon/cfg_files/cccs.conf') is installed and modified if
required.
