Remove silly global_rulesets

A "global_ruleset" would've been a totally wildcard rule, "*".

There are zero of these in the current code, and if there were, I imagine it'd be an error.

Set a smaller LRU rule cache size

After some testing, it's super hard to hit 2,000 entries.

We'll play it safer with lower-ram systems and limit this to 1,000 for now.

Tweak ruleset calculation

Stop building unused test rules for the TLD itself (e.g. www.example.*)

Also remove an intermediate varible assignment.

Add back in TLD rule for google.*

I think this was matching anyway, but let's be paranoid and keep it here for now.
