While directly using busybox[.[no]suid] as the alternatives'
targets, commands could not get correct security labels.

 ~# ls -l /sbin/getty
 ..... /sbin/getty -> /bin/busybox.nosuid
 ~# ls -Z /bin/busybox.nosuid
 system_u:object_r:bin_t:s0 /bin/busybox.nosuid

Add sh wrappers for commands so selinux could work fine.

 ~# ls -l /sbin/getty
 ..... /sbin/getty -> /usr/lib/busybox/sbin/getty
 ~# ls -Z /usr/lib/busybox/sbin/getty
 system_u:object_r:getty_exec_t:s0 /usr/lib/busybox/sbin/getty
 ~# cat /usr/lib/busybox/sbin/getty
 #!/bin/busybox.nosuid
