[HWASan] Ensure RNG is initialized in GenerateRandomTag
Fixes a CHECK-failure caused by glibc's pthread_getattr_np
implementation calling realloc. Essentially, Thread::GenerateRandomTag
gets called
[HWASan] Ensure RNG is initialized in GenerateRandomTag
Fixes a CHECK-failure caused by glibc's pthread_getattr_np
implementation calling realloc. Essentially, Thread::GenerateRandomTag
gets called during Thread::Init and before Thread::InitRandomState:

Also reverts 7a3fb71c3cbdd80666335fa8f6f071b43f0b922a, as it's now
unneeded.
