Dirty hack to support multiple versions of lua in the same machine

This solves the problem of having both lua5.1 and lua5.2 installed on the same machine, Will be nice to test it in the case of having just only version.
It now creates a .so module for each version installed.

Example:
```
λ hilbert radare2-bindings → λ git java* → ls lua/*so*
lua/r_asm.so.5.1  lua/r_bin.so.5.1  lua/r_core.so.5.1
lua/r_asm.so.5.2  lua/r_bin.so.5.2  lua/r_core.so.5.2
```

I think that the valabind-cc wrapper has now more exceptional cases than generic ones, so maybe is a good idea to try to refactor it.
