system/skeleton: update etc/mtab with a more sensible link

Currently, our /etc/mtab points to /proc/mounts. This was all neat so
far, and was good for a sysv-like init system.

However, the way today is to point it at /proc/self/mounts, the
per-process mount tab.

Additionnally, that's what systemd expects. If /etc/mtab is not a
symlink to ../proc/self/mounts and the rootfs is readonly, systemd would
whine loudly (and a service unit would be marked failed).

Since it works well for sysv-like init systems too, just use that.
