Simplify test script

Interestingly, even before this commit and despite using `xvfb` a bunch of errors are printed during Linux tests, but they seem to run successfully to completion:

[5300:1222/133804.075080:ERROR:bus.cc(407)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")
[5323:1222/133804.332045:ERROR:viz_main_impl.cc(196)] Exiting GPU process due to errors during initialization
[5333:1222/133804.352286:ERROR:command_buffer_proxy_impl.cc(127)] ContextResult::kTransientFailure: Failed to send GpuControl.CreateCommandBuffer.
