sr: Add fstools, update build configuration

 * Make sure we create any dirs before trying to put symlinks in them
 * Create a new "fstools" target which aggregates all of our filesystem
   tools into a single multi-call binary. This reduces the overall
   recovery image size by a megabyte, and also removes GPL code from the
   main recovery binary.
