meta-qt5-extra-music-world: remove lsp-plugins for now

* They don't build if libsndfile-dev packages are not installed on build host.
  Laughing matter: This was detected by reinstalling one of my build machines -
  all others machines had libsndfile-dev so this remained undiscovered.
* Even if building: lsp-plugins crash with 'illegal instruction' on Raspi.
  ARMv7 assembler code within lsp-plugins seems to cause trouble for cortexa7..
