Caio Oliveira 30ecaf6689 meson: Only use fallback for Lua if building freedreno tools
This keeps the allow_fallback behavior for Lua dependency when freedreno
tools are used, like it used to be.  But will disable the fallback
mechanism otherwise.

For Intel, the dependency is optional and the tool that uses is
skipped when Lua is not available, so it is fine we don't use fallback
there.
