support/download: introduce curl backend for FTP transfers
Recent versions of wget, starting with wget 2.0, aka wget2 thereafter,
no longer support FTP (nor FTPS, aka FTP-over-SSL). wget2 is packaged in
Fedora 40, recently released; F40 does not even have the old wget
available in its repository anymore.
Introduce cURL as a download backend, that we use for FTP and FPTS
protocols.
Note that the -q flag does not means being quiet; it means that a curlrc
file should not be parsed. The long option is --disable, which meaning
is not much more obivous than the short -q. It also has to be the first
option on the command line.
