[Rpm-maint] [PATCH 1/2] Fix --without-lua build.

[Mark Wielaard]

commit 62bd62 "Add a rpmlua wrapper function for registering libraries"
moved the rpmluaRegister function definition into rpmio/rpmlua.h and
added an #include <lauxlib.h>. This made that file not compile anymore
when lua-devel isn't installed and configuring --without-lua. Even though
that function isn't compiled or used when not using lua with rpm.

Fix this by wrapping both the include and the function definition
in #ifdef WITH_LUA.
