This fixes repart's, systemctl's, sysusers' and tmpfiles' specifier expansion to honour the root dir specified with --root=. This is relevant for specifiers such as %m, %o, … which are directly sourced from files on disk. This doesn't try to be overly smart: specifiers referring to runtime concepts (i.e. boot ID, architecture, hostname) rather than files on the medium are left as is. There's certainly a point to be made that they should fail in case --root= is specified, but I am not entirely convinced about that, and it's certainly something we can look into later if there's reason to. I wondered for a while how to hook this up best, but given that quite a large number of specifiers resolve to data from files on disks, and most of our tools needs this, I ultimately decided to make the root dir a first class parameter to specifier_printf().
