Fix clang thread-safety-pointer warnings

Browse Source 
Clang's -Wthread-safety-pointer warnings will become part of -Wthread-safety in
some future release. Add missing annotations for functions that pass the
address of guarded members. No functional change. Fixes the following warnings:

util/cache.cc:220:17: warning: passing pointer to variable 'in_use_' requires holding mutex 'mutex_' [-Wthread-safety-pointer]
  220 |     LRU_Append(&in_use_, e);
      |                 ^
util/cache.cc:235:17: warning: passing pointer to variable 'lru_' requires holding mutex 'mutex_' [-Wthread-safety-pointer]
  235 |     LRU_Append(&lru_, e);
