output: drop direct scan-out check in output_basic_test()

wlr_output is not well-suited to checking whether direct scan-out
is happening or not. Compositors may want to use their own external
swapchains, for instance.

Additionally, ab7eabac84 ("output: leverage
wlr_output_configure_primary_swapchain()") makes it so
output_basic_test() is called before the output swapchain is
initialized, resulting in false positives.
