service: drop support for SysV scripts for the early boot

This remove distro-specific support for early-boot SysV init scripts.
(And leaves support for normal SysV scripts untouched).

If distributions wish to continue to allow early-boot SysV scripts in
their distribution-specific way they should either maintain this patch
downstream manually, or write a generator for them, or simply ship all
those scripts with a .service wrapper.
