tvheadend htsp client missing after upgrade to librelec 12

  • Major version update normally triggers add-on updates (as new repo, with new higher-versioned add-ons available) but on first boot the existing old-version add-ons will start/run and then updates will happen. With LE12 on an RPi4 the LE11 "arm" CPU arch add-ons are no longer binary compatible with the LE12 "aarch64" userspace and don't run, spewing some messages. Once the normal wave of add-on updates are processed you have aarch64 compatible versions of add-ons installed and all is good again.
