flua: kick out the remaining builtin modules

Bootstrap flua has some magic now to handle modules by building them in
and discovering them via linker sets.  This is slightly cleaner than
always building them in and baking them into loadedlibs for both
bootstrap and system flua.

Adjust the stand build now that these three libs have their own new
homes.
