gl/tests: fix shader creation tests part 2

Continuation of 4fd7a2c783e96e5ebec513f8fd178ba34b2a527f

We check the availability of the high precision floats in GLSL shaders
which involves an OpenGL call and thus is required to be executed on the
OpenGL thread.

The tests were not respecting that and could fail on more strict
drivers.

Tests update for 675415bf2ea9ddc75ea5e5b6eae9ae942c19d6dc
Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/590
