s390/Kconfig: remove obsolete configs SCHED_{BOOK,DRAWER}

Commit f1045056 ("topology/sysfs: rework book and drawer topology
ifdefery") activates the book and drawer topology, previously activated by
CONFIG_SCHED_{BOOK,DRAWER}, dependent on the existence of certain macro
definitions. Hence, since then, CONFIG_SCHED_{BOOK,DRAWER} have no effect
and any further purpose.

Remove the obsolete configs SCHED_{BOOK,DRAWER}.
