<sys/malloc.h>: Reduce kmalloc() implicit requirements on <sys/systm.h>.

 Use __builtin_memset() directly.  Use of __DEQUALIFY() not needed here.

 The "#if 1" case already makes use of __builtin_constant_p() compiler
 extension that we do not have feature check in <sys/cdefs.h> (using
 "#if __GNUC_PREREQ__(2, 0)" should be good enough).

 This finally decouples <sys/malloc.h> from <sys/systm.h> bzero() macro
 visibility (also in "#if 1" block).
