Aurelien DARRAGON 04a4d242c9 BUG/MEDIUM: stats-file: fix shm-stats-file recover when all process slots are full
Amaury reported that when the following warning is reported by haproxy:

  [WARNING]  (296347) : config: failed to get shm stats file slot for 'haproxy.stats', all slots are occupied

haproxy would segfault right after during clock update operation.

The reason for the warning being emitted is not the object of this commit
(all shm-stats-file slots occupied by simultaneous co-processes) but since
it was is intended that haproxy is able to keep working despite that
warning (ignoring the use of shm-stats-file), we should fix the crash.

The crash is caused by the fact that we detach from the shared memory while
the global_now_ns and global_now_ms clock pointers still point to the shared
memory. Instead we should revert to using our local clock instead before
detaching from the map.

It should be backported in 3.3
