Don't spin when polling /dev/random. We also remove the use of spin locks when opening the persistent fd for platforms that require it. For both these cases, we can just use the pthread lock/unlock methods in libc. This includes adding Mutex and DropGuard abstractions. Signed-off-by: Joe Richey <joerichey@google.com>
