The crashreporter feature (and thus, the whole frame visibility) depends
not on OS, but on the HAVE_FEATURE_BREAKPAD define. No need to control
the checkbox visibility separate from the label, when we can show the
whole frame selectively.
The quickstarter feature is only available on Windows, since the systray
support was removed in commit 3e9c908b73
(remove Linux ("UNX") systray "Quickstarter", 2018-05-23).
