Fix ODBC types to match standard typedefs

[EssGeeEich]

This fixes a bug that I'm currently experiencing reproducible in the following way:

• Use lua5.3
• sizeof(long int) must be 8
• sizeof(SQLINTEGER) must be 4
• Select some integer values

Selecting a column of integer type would mess up the values.

Current behavior: 4 is the "got" size, the mess of numbers is the returned value.

Updated behavior: 4 is still the "got" size, the value "2247" is correctly returned.
