tdf#150452: Revert "tdf#130795 use concurrent hashmap in SharedStringPool"

This commit reverts 3749d9af3745c0eaff7239e379578e4e2af89e9d
which removes the dependency on the external library cuckoo

Without using cuckoo the same file in tdf#130795 takes

real	0m4,892s
user	0m5,298s
sys	0m0,449s

With it, it takes

real	0m4,914s
user	0m5,276s
sys	0m0,444s

pretty much the same time
