Fix repair difficulty for combat blouse and shirt

Summary

Bugfixes "Fixed repair difficulty for combat blouse and shirt"

Purpose of change

Combat shirt has its repairs_like set to combat blouse, which doesn't have a recipe, which means both items have insanely high repair difficulty.

Describe the solution

I set the repairs_like to trenchcoat (to match the other army jackets) on both items, so now the repair difficulty is in line with similar gear.

Describe alternatives you've considered

Setting it to another more difficult item, since it is a different material after all, but I think this is at least better than it was in any case so I'd rather lean towards being consistent with similar items.

Testing

I tested repair difficulties before and after. It's now possible to repair these items without having a Ph. D in tailoring.
