i965: Disable ARB_fragment_shader_interlock for platforms prior to GEN9
ARB_fragment_shader_interlock depends on memory fences to
ensure fragment ordering and this ordering guarantee is
only supported from GEN9 onwards.
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109980
Fixes: 939312702e35 "i965: Add ARB_fragment_shader_interlock support."
