ARROW-17496: [Go] Fix Nightly Build (#13943)

Turns out that the `pragma_table_info` function in modernc.org/sqlite's package doesn't work correctly in go1.17 either, only in go1.18. As this is only used for testing and the example sqlite flightsql server, rather than anything needed in the flightsql package itself, the bulid failure is easily solved by marking the example and its tests to be only built in go1.18.

As we already have a git workflow that runs with go1.18, the CI will still continue to test the example code, but mamba builds using go1.17 won't break anymore.
