Subject: Keep the Lua-less build compiling

`cgit_abort_filters` unhooks the Lua write interposer under NO_LUA
too, where neither the hook nor its state exists, so `make NO_LUA=1`
and the default mode of `tools/release-build.sh` have not compiled
since the die path learned to take stdout back from a filter. The
suite now builds that variant into `build/nolua` and runs it, and a
`lua:` filter in such a build is refused with a message naming the
cause instead of an unknown filter type.
