Fuse the proclist into the root node

* dircat.c, dircat.h: New files, merge directories.
* Makefile: Add the dircat module.
* main.c: Use dircat to merge the proclist into the root
  directory, instead of having it as a stand-alone one.
* procfs.h, procfs.c: Add a "refresh hack" to have the
  contents of the root directory recreated on each request.
* proclist.c (proclist_make_node): Enable the hack in question.
