Fixed arrays expansion.

There were two problems with njs_array_expand():

 1. It checked that the requred size with the appended elements wasn't bigger
    then the array size and then did nothing.  If there were elements removed
    from the beggining (by shift() operation), then "size <= array->size" can
    be true even if there wasn't enought free space after the array.

 2. After allocating more space to prepend elements, it set array->size without
    counting those elements.

Probably, the original idea was to decrement array->size while removing
elements from the beginning, but it wasn't done right.  Even if so, the
new version of the function looks cleaner.
