[PATCH 1/3 V3] kea: fix creating runtime directory in service files

[Yi Zhao <yi.zhao@windriver.com>]

Create runtime and state directories using RuntimeDirectory and
StateDirectory in systemd service files, rather than creating them via
ExecStartPre. This is a standard approach for systemd[1]. When the
server starts, systemd will automatically create these directories.

Also, add more configuration files to CONFFILES.
