fix(mangohud): support 32bit apps (pacstall#6342)

update script to latest specmangohud support 32bit games via 2 builds +
installs, one for mangohud default (64bit) and one for 32bit

the problem with the current script is, that old games (or other 3d
apps) built for 32bit are not supported by the default mangohud build. I
adapted the script to build 2 mangohud versions, the default one
(resulting in 64bit mangohud install) and a second one for 32bit.
Both work together nicely, I tested it by removing all mangohud from my
install, then running the new script, then testing a modern game
(wreckfest in my case) and an old one (WoW 3.3.5a private server ~2010
(32bit)). both work fine.
