[OE-core] [PATCH 5/7] systemd-systemctl-native: simplify and support preset-all

[Jonas Bonn]

Now that the systemd class sets up service presets instead of actively
enabling services, the 'enable' and 'disable' subcommands for systemctl
are not actually used anywhere.  As such, we can remove these to make
sure that nobody inadvertently introduces new uses of them.

We do, however, one case where the enable/disable machinery is still
required; that is for the read-only-rootfs case where the 'preset-all'
command can not be called at runtime but needs to be called when creatng
the image.  For this case, we implement 'preset-all' here.

There was also a previous implement of 'preset'... not sure that this
ever worked as the implementation looks bogus and there aren't any users
anyway.  This patch removes the 'preset' subcommand, as well.
