swupdate: reboot on update from initramfs recovery image

Create swupdate-progress-sysvinit and swupdate-progress-systemd packages with
the necessary startup scripts for swupdate-progress to run correctly during
startup for both virtual/init managers. swupdate-image initramfs should RDEPEND
on swupdate-progress-sysvinit, which now adds a dependency on the swupdate-progress
binary (packaged in swupdate-progress-bin).

This allows swupdate-progress to simultaneously be installed in both a distro's
main rootfs which uses the systemd DISTRO_FEATURE, and the initramfs image which
uses sysvinit.

The old swupdate-progress package is now empty, and can still be used as an
RDEPENDS on the main rootfs image recipe, and swupdate will automatically
select the appropriate startup script based on DISTRO_FEATURES.
