packagegroup-meta-oe: fix lvgl inclusion

Since commit f7fedd1 ("lvgl: Upgrade to LVGL 9 series"):
* lv-drivers and lv-lib-png packages do not exist anymore
* lvgl does not depend on "wayland" being in DISTRO_FEATURES

This fixes these warnings (e.g. from AB[0]):
  Nothing RPROVIDES 'lv-lib-png' (but [...]/packagegroup-meta-oe.bb RDEPENDS on or otherwise requires it)
  Nothing RPROVIDES 'lv-drivers' (but [...]/packagegroup-meta-oe.bb RDEPENDS on or otherwise requires it)
