daemon for no-MMU no-threads and CLONE_VM

I saw a problem building uClibc for a no-MMU, no-threads configuration
where CLONE_VM was undefined when building daemon.
CLONE_VM is defined in <bits/sched.h>. A build with threads ends up
including <sched.h> via <pthread.h> via <bits/uClibc_mutex.h>; this
indirect include does not happen for a build without threads. Does anyone
see anything wrong with this patch to add an explicit <sched.h> include to
daemon.c?
