[PATCH 5/5] Implement /proc/mounts as a symlink to /etc/mtab |

Among other things, many parts of Debian-installer want /proc/mounts.
Implementing it the right way is non-trivial, though. In the meantime,
we publish a symlink to /etc/mtab so that the user can fake it in
whatever way they want. Furthermore I hope to be porting busybox mount
soon, and use it to manage the mtab in d-i.
