Currently Gallium has no way to activate the
'force_glsl_extensions_warn' workaround that allows
buggy apps that use GLSL extensions without asking for them to work.
Since gallium mesa state tracker is essentially split into two,
(dri (src/gallium/state_trackers/dri) and mesa (src/mesa/state_tracker))
and only former has access to driconf options while later knows nothing
about dri, I added this support by reading an environment variable.
export force_glsl_extensions_warn=true
