• Updated sync_threshold_deletes and sync_threshold_updates to trigger
  when the file count is equal to or greater than the threshold
  (previously only greater than). This allows using a value of 1 to
  abort on a single file deletion or change.
  This change has effect only with SnapRAID CLI 14.4.
• Removed the default "run_as_user nobody" from the example .conf file.
  It was too strict a requirement for running external tools and
  incorrect on Windows.
• Made the presence of the zip tool a strong requirement for building
  from source.
• Made systemd detection when building from source independent of the
  presence of pkg-config.
• Remove redundant ExecStartPre config check and explicit --conf
  argument from the service file, as the daemon resolves its
  configuration path internally with fallback to /etc/snapraidd.conf.
• Renamed "block_count" to "blocks_count" and added some missing
  "format: int64" entries in the snapraid.yaml to match the API
  results.
