shellcheck / shellcheck (push) Failing after 16s
voxtype's build from source fails now and then at link time, with
Vulkan shaders missing: 0c0ddf5 built it in two runs and not the third,
with the same packages. The baseline isn't what's under test, and the
old installers skip what they already installed, so try once more.
