[OE-core] [PATCH] systemd-systemctl: Add preset capability

systemd has presets as described here
http://lists.freedesktop.org/archives/systemd-devel/2011-July/002830.html
This patch will let distros define presets file
which will override the enable/disable specified
by recipes.
systemctl preset without any argument will run presents
on all services
systemctl preset service1 service2 will run presets on
specified pervice.
something like enable * or disable *
would mean that all services will be either enabled or
disabled by default.
If no user-presets are specified then 'enable' is default
systemd allows basic globs but we do not implement them
except '*'
