Solo mode doesn't recognize Kodi running, launches second instance on emu close

[grnassar]

Another easy one. I noticed Solo mode wasn't closing Kodi; didn't care much until everything started slowing down a lot the more I tried it.

applaunch.sh is looking for kodi.bin, but the binary was renamed in Matrix. Now the name depends on your compositor -- kodi-x11, kodi-gbm or kodi-wayland. kodi.bin is no longer used at all. Edited applaunch.sh to look for the right process names, solved the problem -- pull request coming in a jiffy.

Crud. That's what I get for using the new app. It didn't branch the fork like I wanted it to and now it's put both this and #440 under the same pull request. My apologies. Should still work fine, of course, and at least both are simple changes so chance for conflicts are low I guess. Won't make that mistake again, though!
