We get the path to our executable via a readlink() on
"/proc/self/exe", which appends a " (deleted)" during
package reloads.

To ensure the new process' parent is pid 1, so systemd won't
complain about supervising a process it does not own.
Fixes the following log spam on reloads:
Apr 25 10:50:54 deb-dev systemd[1]: proxmox-backup.service: Supervising process 1625 which is not our child. We'll most likely not notice when it exits.

Now that we let hyper shutdown gracefully we need an owned
version of the listening socket to prevent it from closing
before running the reload preparations.

Reloadable resources are now 'Reloadable' instead of
'ReexecContinue'.
The struct handling the reload is a 'Reloader', not a
'ReexecStore'.

Proxy and daemon for now just want to handle reload via
`SIGHUP`, so provide a helper creating the signalfd stream
doing that - this is simply a filtered stream which passes
the remaining signals through, so it can be used exactly
like the signalfd stream could before to add more signals.
