Proof of concept of sqlite serialization (#436) 
* Proof of concept of sqlite serialization

This is a minimal proof of concept in order to show that it is easily possible to store the sqlite database within the zip file itself not requiring creating an external file first. Changes include compiling the sqlite library with the serialization flag, adding serialize/deserialize to the lua sqlite library and demonstrating the work via the redbean demo.

* Change demo for sqlite serialization

As explained in https://github.com/jart/cosmopolitan/pull/436#issuecomment-1164706893 the original use case is not possible with sqlite serialization, as an in-memory database cannot be shared across multiple processes. Thereby, this use case simply creates a backup of the in-memory database created in '.init.lua' and loads it to do a query.

* Fix sqlite3_deserialize parameters

The call to the sqlite3 library for the deserilization wasn't fully correct. This should fix the size parameters.

# Please be warned that locks currently do nothing on Windows since
# figuring out how to polyfill them correctly is a work in progress
# Further note we currently don't do that thing SQLite does for Mac
# file locks so your dbase will only be as reliable as Apple wanted
# it to be when they wrote their POSIX file locking implementation.
