Eelco Dolstra b352fe2775 Revert "Scan /proc/<pid>/cmdline for GC roots"
This reverts commit 194e3374b8.
Checking the command line for GC roots means that

  $ nix-store --delete $path

will fail because $path is now a root because it's mentioned on the
command line.

For instance, this prevents paths from being deleted that are in use
by a "nix-build --run-env" session.

Eelco Dolstra a8ea4cbcc8 * Scan /proc/sys/kernel/modprobe for roots to prevent the kernel
modules for the running kernel from being garbage-collected.  Idem
  for /proc/sys/kernel/fbsplash.

Eelco Dolstra ebcccbd358 * Added a tool to find additional roots for the garbage collector,
such as open files, current directories, mmaped files, etc.  This is
  inherently unportable, but it's easy to adapt this script to other
  platforms.  Currently we call `lsof' and try to read various bits in
  /proc/NNN.

  The goal is to prevent the garbage collector from removing store
  paths that are no longer reachable from a permanent root but that
  are still in use (for instance, after the user has done "nix-env -e"
  on a running program).
