lib: increase refcount when returning cached module instance
Subsequent requires of the same module returned the cached module instance
without increasing the refcount, leading to use-after-free on VM tear down
or garbage collection cycles.
Solve this issue by properly incrementing the refcount before returning
the cached module instance.
Fixes: #25
Fixes: 96f140b ("lib, vm: ensure that require() compiles modules only once")
