chore: minor changes to MePo (#10917) 
This PR makes minor changes to the MePo premise selection algorithm.

I'm increasingly believing that MePo will not work well in Lean; I've
tried a few things without success. Alistair Geesing's thesis from 2023
had similar conclusions.

My intention is to reach the point we can properly benchmark premise
selection algorithms before doing any more work here.
