- remove 00-zipl-prepare.install plugin that is not needed anymore

The kernel-install plugin removed the "${BOOT_DIR_ABS%/*}" directory that
was created unconditionally by the kernel-install script. Since the other
plugins used the existence of this directory as the indication on whether
systemd-boot was used or not.

But now the kernel-install script doesn't unconditionally create this dir
anymore and if $BOOT/$MACHINE_ID exists, so there's no need anymore to do
any cleanup.
