found another small bug/issue, which will impact probably nobody, inxi was using an obsolete kde command

kde-config rather than the current: kde4-config, so now it tests if the commands exist, tries kde4, then kde5 then kde

this is probably not used by any distro so it does not matter, but it was wrong so it's fixed now.
