community/soc-qcom-msm8916: Add a workarund for GTK4 (MR 4958)

GTK4 has switched to a new renderer. Unfortunately adreno a306 is
effectively abandoned in mesa and has many bugs which the new GTK
renderer now hits.

To allow us to still use GTK4 apps on the msm8916 based devices, force
the old renderer on them for now.

Fixes: #2681
[ci:skip-build]: already built successfully in CI
