ash: allow wait to handle more than 64 processeswaitfor

WaitForMultipleObjects() can only handle 64 processes (actually,
MAXIMUM_WAIT_OBJECTS) in a single call.  Using the 'wait' shell
built-in after a command like:

   for i in $(seq 1 70); do echo $i; sleep 10 & done

resulted in an uninterruptible 'wait'.

Handle processes in batches of MAXIMUM_WAIT_OBJECTS.

The problem was noted by Morgan Bartlett, who also supplied a
fix which I claim to have 'improved'.

Adds 32-48 bytes.
