firefox: Enable WebRender by default, bypassing Firefox's internal

soup of checks to see whether the GPU is "good enough" (that has a failure
rate of 100% on NetBSD).  Greatly improves general web page performance,
even with the unaccelerated llvmpipe OpenGL implementation.  Tested
with various Xorg drivers.
