Skip tests/005.phpt

The reason I am marking this test as skipped for the time being is that
I am not sure if this is a bug in the driver or if this is just caused
by me running a newer/older firebird version in CI.

Expected error:
```
lock conflict on no wait transaction deadlock
```

Real error:
```
deadlock read conflicts with concurrent update concurrent transaction number is
```
