install.sh: run post-install script just like .rpm/.deb package

To install scylla using install.sh easily, we need to run following things:
 - add scylla user/group
 - configure scylla.yaml
 - run scylla_post_install.sh

But we don't want to run them when we build .rpm/.deb package,
we also need to add --packaging option to skip them.

Fixes #5830
