negcache: Soften condition for expired entries

Type of timestamp for entries in negative cache is time_t
which is number of *seconds* that have elapsed since 1 January 1970.

The condition for ttl was to strict so entry could be valid
 from  "ttl-1" to  ttl e.g.
 * ttl is 1 second
 * entry was stored to negative cache at 1432120871.999639
   stored_timestamp = 1432120871
 * entry was tested few miliseconds later 1432120872.001293
   current_time = 1432120872

Entry was marked as expired becuase result of condition was false
  stored_timestamp + ttl < current_time
          1432120871 + 1 < 1432120872

This is a reason why ./test-negcache sometime fails.
It's quite easily reproducible on slow machine or when valgrind was used.

sh$ while libtool --mode=execute valgrind ./test-negcache ; do echo OK: done
