lua fixes for distcheck + extras: ci: remove --disable arguments from distcheck

Taking the same ideas as b46611fe, we can ensure the distcheck builds everything when run in the CI, so that the currently disabled modules are built for real and tests can use them. They should stay disabled since they would break distcheck when the mandatory plugins cannot be built, but we can ensure that in the CI in a reliable way.

We use it as an argument to make so that make actually erase the value in the makefile.
