lib/igt_fb: also pass the stride to igt_create_fb_with_bo_size()
If the caller is going to specify a custom size, it's likely that he
will also specify a custom stride. The automatic stride picked by
create_bo_for_fb() is too huge for tiled buffers, so if the caller
wants smaller buffers, then he'll need a smaller stride too, otherwise
the Kernel will reject the addfb IOCTL due to stride * height being
bigger than the size.
I want to make tests/kms_frontbuffer_tracking use
igt_create_fb_with_bo_size() so I can provide smaller buffers that
will fit into the CFB. I'm also planning to make all frontbuffers with
the same width/height/format have the same stride and size regardless
of tiling method so I can exercise specific code paths.
