vold_decrypt: Code cleanup

* Separate stdout and stderr buffers:
  vdc's return codes get sent to stdout, but the possible presence of
  other error messages in the output buffer will cause a valid return
  from vdc not to be parsed properly, and subsequent decryption to fail
  due to "misunderstood" return code.
  eg on the U11+ (htc_ocm) libc will generate an error to stderr due to
  a missing property area resulting a proper connection to vold being
  incorrectly parsed, and breaking decryption.

* Improve logging.
