ghash: Fix entry_is_big for CHERI architecture

Browse Source 
The entry_is_big function checks if an entry fits into a so-called
small entry, i.e. into a guint. This optimizes space for hash tables
on 64 bit system with hash tables containing 32 bit entries.

This code actually checks if the highest 32 bits are set, which would
become an issue with CHERI and its 128 bit pointers.

Helps: #2842
