Summary:
Use another static object to join threads instead.
This change is motivated by a case in which some code using NewLRUCache() -> ShardedCacheBase -> SemiStructuredUniqueIdGen -> GenerateRawUniqueId() -> Env::Default() was happening
during static destruction.
I didn't see anything else in PosixEnv or base classes that would cause a problem by not
destroying. (WinEnv is already not destroyed; see env_default.cc)
