Fix the path for verity_key replacement when signing.

      removed.  Changes are processed in the order they appear.

      Default value is "-test-keys,-dev-keys,+release-keys".

  --replace_verity_private_key <key>

      Replace the private key used for verity signing. It expects a filename

      WITHOUT the extension (e.g. verity_key).

  --replace_verity_public_key <key>

      Replace the certificate (public key) used for verity verification. The

      key file replaces the one at BOOT/RAMDISK/verity_key (or ROOT/verity_key

      for devices using system_root_image). It expects the key filename WITH

      the extension (e.g. verity_key.pub).

  --replace_verity_keyid <path_to_X509_PEM_cert_file>

      Replace the veritykeyid in BOOT/cmdline of input_target_file_zip

      with keyid of the cert pointed by <path_to_X509_PEM_cert_file>

      with keyid of the cert pointed by <path_to_X509_PEM_cert_file>.
