Post-merge fixes for Connect engine

1. define connect_EXPORTS, this causes the engine to use MariaDB
   versions for timestamp<->struct tm conversion instead of
   TZ-dependent libc versions.
2. remove check_access() that was removed once, but re-appeared
   during a complex merge.
3. disable a totally broken test
4. update test results
5. skip odbc_firebird test when no firebird DSN is available
