Run each standalone Lua version once

A plain lua is usually one of the versioned names again, as lua and
lua5.5 are here, so every 5.5 check ran twice, while names such as
lua54 and lua-5.4 were never looked for. A test now names the version
that ran, since "under lua" did not say which one it was.
