tdb2: speed up testing.

The time to run tests under valgrind has become excessive; particularly
the failure tests which fork().   Thus we cut down testing:

1) api-94-repack: reduce from 234 seconds to 2 seconds by cutting
   iterations, despite adding TDB_VERSION1 tests.

2) api-missing-entries: reduce from 17 seconds to under 1 second by
   not checking db inside loop, but at end.

This reduces the total ccanlint time from 729 to 489 seconds.

tdb2: use tdb->flags & TDB_RDONLY instead of tdb->read_only for TDB1 code.

There's also a semantic change here: for tdb1, being read-only meant no
locking, and it was an error to try to lock a r/o database.  For TDB2, you'd
need to specify TDB_NOLOCK, which suppresses locking silently.

This precludes the possibility of using TDB_INCOMPATIBLE_HASH with a
custom hash function: that used to allow the user to ensure that old TDB
versions couldn't open the TDB file (and recent ones check the header to
ensure they're using the right hash).  But that's a small loss.
