Stenzek c82be53d5c GLInterface: Use EXT_swap_control or MESA_swap_control over SGI
The SGI extension does not define calling SwapInterval with a parameter
of zero as valid. It was just lucky that drivers interpreted this as
vsync off. The EXT_swap_control extension defines zero as a valid value.

Mesa does not appear to support the EXT variant, so we fall back to
MESA_swap_control here, which also supports zero.
