revert: fix(kf2): create the KFGame/Cache map-load directory on install (#5108)

This reverts commit bd08aff.

On the current KF2 server build (10897) the server creates KFGame/Cache
itself when it first downloads a Workshop item, so the directory is not
missing. The map-load crash comes from starting directly on a Workshop
map that has not been downloaded yet, which this change does not affect.
