HDDS-2234. rat.sh fails due to ozone-recon-web/build files

[adoroszlai]

What changes were proposed in this pull request?

Make RAT check ignore ozone-recon-web/build directory.

During ozone-recon to recon rename (HDDS-2044) the directory ignored by RAT was changed to recon-web/build, but the real directory is still ozone-recon-web.

The mismatch is not a problem for CI because it doesn't build anything before the RAT check, so the build directory is not present.
