Add pstore-RAM support and fix comments indentation

Check README.MD and /etc/default/kdump for instructions on
pstore usage - should be simple, it's automatically configured.

Notice that we expect all units to have the same e820 memory
map, hence to have the RAM buffer available. This point should
be better clarified by the team working with firmware.

Also, the package now enables the kdump systemd service
automatically, in a post-installer hook.
