  [clang] Attempt to fix "test/Modules/fmodules-validate-once-per-build-session.c"

This test started failing after 7a242387: https://lab.llvm.org/buildbot/#/builders/154/builds/16276. There seem to be two bugs:
* The `-fno-modules-force-validate-user-headers` flag was passed on the wrong line.
* Changing source files was being done without an explicit `sleep`, meaning there was a possibility of the files maintaining their old modification time and not triggering the expected rebuilds.
