BUILD: cache: fix a build warning regarding too large an integer for the age

Browse source 
Building on 32 bit gives this :

  src/cache.c: In function 'http_action_store_cache':
  src/cache.c:466:4: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]
  src/cache.c:467:5: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]
  src/cache.c: In function 'cache_channel_append_age_header':
  src/cache.c:578:2: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]
  src/cache.c:579:3: warning: this decimal constant is unsigned only in ISO C90 [enabled by default]

It's because of the definition below added in commit e7a770c ("MINOR:
cache: Add "Age" header.") :

  #define CACHE_ENTRY_MAX_AGE 2147483648

Just appending "U" to mark it unsigned is enough to fix it. This only
affects 1.9, no backport is needed.
