Victor Hsieh 59183120c2 Initialize fs-verity keys in shell script
This gives us two benefits:
  - Better compatibility to keyctl(1), which doesn't have "dadd"
  - Pave the way to specify key's security labels, since keyctl(1)
    doesn't support, and we want to avoid adding incompatible option.

Test: See keys loaded in /proc/keys
