trans: unlock nodes with faked attributes in fakeroot
When a node has faked attributes, we cannot drop our node.
Reinitialize the lock box as if the node was dropped. This fixes the
following bug:
% fakeroot-hurd /bin/sh -c 'touch /tmp/$$.lock
chown 0 /tmp/$$.lock
l(){ flock /tmp/$$.lock true; }; l; l'
<hangs>
* trans/fakeroot.c (fake_node_dropweak): Unlock the node if the last
real reference is dropped but we keep a fake one.
