[oe] [meta-qt5][PATCH] qtdeclarative: fix build without opengl support

[Martin Jansa]

Can you please test with master-next (where is pending upgrade to 5.10), if
this patch is still needed there?

If you want to use it with 5.9, then try rocko-next (with pending upgrade
to 5.9.3).

All my qt5 builds have opengl enabled, so I haven't seen this issue, but
the patch as is doesn't apply on top of 5.10 upgrade (so I've just dropped
it from master-next).
