Kuba Mracek 6b6d9bbd48 [sanitizer] Avoid calling a nullptr in MonotonicNanoTime if interceptors are not yet initialized 
There's a TSan startup crash on Linux when used in Swift programs, where MonotonicNanoTime will try to call real_clock_gettime and then jump to NULL because interceptors are not yet initialized. This is on Ubuntu 18.04. Looks like TSan's main Initialize() function is called at a point where __progname is already set, but interceptors aren't yet set up. Let's fix this by checking whether interceptors are initialized in MonotonicNanoTime.
