qpkg/prereq.c (resolve): simplify requisites chaining logic

Browse Source 
Tried to keep next_dep at the beginning, but that's actually unnecessary.
The historical background is that the dependency list pointer was
originally thought to point to the list currently being processes. But
since it's a list following it, we don't need to maintain the original
order.
