update-rc.d: don't do anything if systemd.bbclass is inherited

We need the update-rc.d class to work when systemd is being used so that
packages that only have SysV init scripts still work.  However if a recipe
supports both we don't want to install SysV and systemd files under systemd.

To solve this, before doing real work in update-rc.d check if the systemd class
has been inherited and don't do anything if it has.
