Add Centos-8 support

Reverting patch https://review.opendev.org/#/c/709532/ which is installing lsyncd using source
but now el8 epel repo providing distro rpm for lsyncd so we don't need to install from source.
also changing lsyncd.conf.lua path to /etc/lsyncd/ for centos8 support.

adding rsync-daemon rpm because centos8 islocated daemon and client in seperate package.
