test: mark 'test/parallel/test-sqlite.js' as flaky

The current test is large and can time out. It should be split
into multiple smaller tests as done in nodejs#54014. However, that
approach appears to change GC behavior such that the database
files are not cleaned up quickly enough on Windows. Forcing
any unfinalized SQL statements to be GC'ed appears to fix the
problem. Mark the original test as flaky until the necessary
code changes are made.
