Subject: [PATCH] ci/test.lua: fix string splitting

string:split() isn't part of the standard library, but is defined if
`gui/load-screen.lua` is run. This happens in the default dfhack.init-example
and on GitHub Actions, but not on Buildmaster.

This is an intermediate solution to get CI working again. A more complete
solution would be to move string:split() to dfhack.lua, like
string:startswith(), or to take a pass over scripts and make sure they aren't
modifying built-in types like string/table.
