modesetting: Disable reverse prime offload mode for displays running on evdi,udl

This mode for displays running on evdi/udl as side effect of failed glamor_egl_init
reverse_prime_offload_mode was initialized to FALSE

After Mesa upgrade to 21.0.0 GL_RENDERER is not llvmpipe that results in successful glamor_egl_init
and reverse_prime_offload_mode enabled.

This commit is explicitly disabling reverse_prime_offload_mode for evdi and udl drivers
