Subject: [PATCH] Add `--check`, `--rdfind`, `--no-rdfind` options to
 `install-onlyoffice.sh`

`--check` is useful for anyone who wants to check if their OnlyOffice
installation is up to date without actually installing it.

The `--rdfind/--no-rdfind` commands serve a few purposes:

1. It makes it clear that `rdfind` can still run even if you specify `--check`.
2. People can ensure that `rdfind` runs by specifying `--rdfind`, which
   helps if they accidentally uninstall `rdfind`.
3. People can now skip running `rdfind` even if they have `rdfind`
   installed.
