hooks: drop namespace references before post-stop

Browse Source 
Callers such as LXD run post-stop hooks to perform cleanup operations on
shutdown. This can involve umount and other things. To avoid surprises with
lingering namespace references we should close all our namespace-preserving
file descriptors. We don't need them at this point anymore anyway.
