[pve-devel] [PATCH installer] post-hook: save post hook data to /run/proxmox-installer

Having the sent post-hook data available somewhere in the installatino
environment after the fact is seful for easily inspecting a
failed/rejected post-hook.

It's a rather niche thing and more useful to developers than users.
Added this while working on the PDM integration, and thought it might be
nice to have this in general, especially since it does not have any
other impact.
