nix: Bake the ODBC configuration path into unixODBC.

Browse Source 
The previous method seems to be failing; we're not finding the drivers. Rather than using environment variables to tell unixODBC where to find odbcinst.ini, we can instead just configure it to point to the correct location and bake it into the binary.

This means we need to build unixODBC ourselves, but it's pretty quick, so doesn't seem like much of an issue.
