After commit 043b3f7b6388 ("lib/list_sort: simplify and remove
MAX_LIST_LENGTH_BITS"), list_sort.c no longer uses ARRAY_SIZE() (which
required kernel.h and bug.h for BUILD_BUG_ON_ZERO via __must_be_array)
or memset() (which required string.h). As these headers are no longer
needed, removes them.

There are no changes to the generated code, as confirmed by
'objdump -d'. Additionally, 'wc -l' shows that the size of
lib/.list_sort.o.cmd is reduced from 259 lines to 101 lines.
