dist/debian: install capabilities.conf on postinst script

We still has "{{^jessie}}" tag on scylla-server systemd unit file to skip using AmbientCapabilities on Debian 8, but it does not able to work anymore since we moved to single binary .deb package for all debian variants, we must share same systemd unit file across all Debian variants. To do so we need to have separated file on /etc/systemd to define AmbientCapabilities, create the file while running postinst script only if distribution is not Debian 8, just like we do in .rpm.
