[build-script] Don't run lit tests separately
[build-script] Don't run lit tests separately

With the recent changes upstream we use lit as the test driver for CMake
based builds. Instead of invoking lit and dotest separately, we need to
pass the dotest arguments to lit and have it take care of everything for
us.
