config: Enable IORap app launch prefetching

Commit b73d5516136d1a4de39afd74f564daf70b946889 in build/make (rvc-qpr2)
disabled IORap by default due to a "regression" without mentioning what
the regression is. Considering how it's been working fine for the past 6
months and has demonstrated improvements to app launch time [1], let's
re-enable it here.
