  Force static value for LUAL_BUFFERSIZE

In Lua 5.3.3, LUAL_BUFFERSIZE always equaled the constant since LUA_FLOAT_LONGDOUBLE was always defined.
This check changed in 5.3.4 and the alternate path was being used for LUAL_BUFFERSIZE and triggering
old-style cast warnings in Scons + GCC. Hopefully this gets fixed for 5.3.5.

The following patch constitutes the changes (though they were applied by hand):
