Michael Tretter ac393aa657 qml6glsink: add support for texture-target external-oes
In order to use oes-external, the qml6glsink needs a fragment shader that uses
the samplerExternalOES.

The qsb tool is not able to handle shaders that contain samplerExternalOES since
this feature is not supported by all target shading languages. The qsb tool is
able to replace a shader in the qsb file to handle this use case. Use it to
generate a shader variant that uses samplerExternalOES for OpenGL ES and select
that variant if the qml6glsink negotiated texture target oes-external.
