lv2-turtle-helper: handle inifite qemu runs as error

Browse Source 
distrho-ports ttl generation with qemu has alway been pain: For unknown reasons
some plugins caues qemu to run infinite. Up to now we could ignore particular
plugins by adding them to LV2_PLUGIN_BLACKLIST_QEMU} but since the affected
plugins change from time to time maintaining this turned into pain. So handle
infinit qemu runs as error. To achive we:

* add qemu-with-timeout-native which injects coreutils' 'timeout' into command
  line by creatin wrappers for all qemu-* available
* rework qemu-ext-musicians.bbclass (was renamed to avoid conflicts with
  meta-qt5-extra's qemu-ext)
* rework lv2-turtle-helper.bbclass and adjust logs
