Make use of all Qt features conditional that are not supported on the
web assembly platform (mainly TLS support and QProcess).
Note that HTTPs is supposed to work nevertheless as long as the certificate
matches (with the usual corss-site scripting limitations).
This is the same as the feature already present in the launcher and
connection settings. Not sure how much sense it makes for systemd services
as they run rather independently from the UI but maybe it is useful.
