util.crypto: Use Lua 5.2 API for predictable buffer size

Browse source 
In Lua 5.3 LUAL_BUFFERSIZE is a macro computed from sizeof and is thus
not known at pre-processing time, so this does not work.

Since Lua 5.1 is no longer supported, we can use luaL_prepbuffsize()
which is available from Lua 5.2
