change columnstore debian package name from cmake

First package is how our debian package names looks like

mariadb-columnstore-1.1.2-1-x86_64-stretch-client.deb

name after going though the repo scripts:

mariadb-columnstore-client_1.1.2_amd64.deb

This is for all columnstore, api, and data adapters. Need to change the CMAKEs to where it looking like or simular to the package names that is generated from the deb repo tool as shown above.

1, x86_64 needs to change to amd64
2. client name needs to be moved forward
3. need more info on this, do we keep the OS name in the package.
