use a single cImport

Two cImport calls generate incompatible code: we can't use the structs
generated in sqlite.zig in functions in errors.zig for example

Up until now it wasn't actually a problem since in errors.zig we only
ever used constants which does work, but now we want to introduce
functions in this file.
