sign_rpm: support signing files in RPM payload

Currently, RPM4 supports to sign the files in RPM payload with plugin
mechanism. We introduce more definitions to make the file signing
available for the users:

- RPM_FILE_CHECKSUM_DIGEST
  Global switch to enable file signing.
- RPM_FSK_PATH
  The file signing key.
- RPM_FSK_PASSWORD
  The password of file signing key.
- RPM_FILE_CHECKSUM_DIGEST
  The file checksum digest.
