Port cryptfs to HILD keymaster HAL

Cryptfs uses keymaster for key derivation. Vold has a C++ abstraction
for Keymaster. However, cryptfs, being a pure C implementation, uses
its own abstraction of the keymaster HAL.

This patch expresses cryptfs' keymaster abstraction in terms of
vold's C++ Keymaster abstraction, consolidating the code base to a
single point where the actual keymaster HAL is beeing used.

Test: successfully upgrade bullhead/angler while using FDE and
      having a PIN set
      run vold_cryptfs_scrypt_hidlization_equivalence_test
