[klibc] [PATCH 3/3] kinit: Add callsites to execute files in drop-directories.

[Mike Waychison]

This patch adds two callsites where kinit will go off and execute
executable files in hard-coded drop-directories.

We introduce a drop-directory at
  /scripts/after-network: ipconfig is completed, but the root
      filesystem isn't yet mounted.
  /scripts/after-mount: the root filesystem is mounted at /root.
