[util] Unify Borderlands games fixes

[Tiagoquix]

This PR unifies utility fixes for Borderlands, Borderlands 2 and Borderlands: The Pre-Sequel.

Motives:

• BO2 and Pre-Sequel currently share the same fixes.
• BO has one of the fixes that BO2 and Pre-Sequel have.
• The three games were made by a common developer: "Gearbox Software".
• The three games were published by the same publisher: "2K Games".
• The three games use Unreal Engine 3.
• The release dates are, respectively: 2009-10-26, 2012-09-18 and 2014-10-14 (not too much time difference between releases).

These changes were not tested. However, I think they won't cause problems (if there are any).

Thanks to fuzzyquils and pixelcluster for helping me to craft the necessary RegEx on Discord.

I don't think all these games being from Gearbox is a good reason to enable more workarounds for the original game? Do we have proof that they are needed?

Do try to test these things, since merging untested stuff is generally not a good idea. We sometimes get regressions even with tried and tested changes.

However, I think they won't cause problems (if there are any).

Do they help in any way though? Having a more compact config entry isn't a goal in itself.

Fair point then. I cannot test all the fixes because I do not own the first game. I'll make a separate PR to address a different issue regarding those fixes.
