d/postinst: do not break, if ipam-file moves fail

failing a package-install does not help repairing the situation - so
inform the user about the issue instead of erroring out. The copy
could fail if a node is not quorate, so writes in /etc/pve are a bit
more likely to fail
adapts the change introduced in
d0628df ("debian: migrate legacy mac/ipam cache/state files")
