Pin SQLAlchemy compliance baseline for rowcount, lastrowid, empty inserts

The Requirements class already documents a block of "baseline
declarations mirroring SQLite behavior" so a future maintainer running
the SQLAlchemy compliance suite has a single source of truth. Four
flags that match the same pattern were missed: sane_rowcount,
sane_multi_rowcount, emulated_lastrowid, supports_empty_inserts.
All four hold for dqlite today — the server forwards
ResultResponse.rows_affected / last_insert_id verbatim, executemany
aggregates per-iteration rowcounts, and INSERT ... DEFAULT VALUES is
regular SQLite syntax. Pin them open() alongside the others and extend
the exclusion-object test to cover the new names.
