Not handling symlinks correctly (whatever "correct" means) would break
other uses of febootstrap, too, so I think that it makes sense to handle
this in febootstrap.

On a Squeeze system (6.0.1 according to /etc/debian_version), /var/lock
and /var/run are still normal directories. The change that broke the
test must have been introduced later. (The workstation I tested this on
runs unstable.)
