package/rsync: bump version to 3.2.3

package/rsync: bump version to 3.2.3

- disable simd, openssl, xxhash, zstd, lz4, asm options

- update COPYING hash (add openssl and xxhash license
  enhancement):

  In addition, as a special exception, the copyright holders give
  permission to dynamically link rsync with the OpenSSL and xxhash
  libraries when those libraries are being distributed in compliance
  with their license terms, and to distribute a dynamically linked
  combination of rsync and these libraries.  This is also considered
  to be covered under the GPL's System Libraries exception.

For details see [1].
