pgsql: Add valgrind suppression for pg_atomic_init_u64.

Add valgrind suppression for pg_atomic_init_u64.

pg_atomic_init_u64 (indirectly) uses compare/exchange to guarantee
atomic writes on platforms where compare/exchange is available, but
64bit writes aren't atomic (yes, those exist). That leads to a
harmless read of the initial value of variable.
