oracle-xe: Add new package, version 11.2.0.

This is the Oracle Database which they give out for free, therefore it's called
Express Edition.

Well, I pretty much packaged this in vain as I finally found out that i don't
need that Oracle Database stuff at all. And my original purpose was to do SQL
query/constraint testing.

So before I'm going to throw this away (forever, oh no!), maybe someone else
might have a use case for this.
