cheri: malloc: Disable pointer protection
Such arithmetic invalidates capabilities so this security measure does
not work for CHERI.
Note: the architecture makes it hard to corrupt pointers in malloc
metadata, but not impossible: current allocation bounds include the
metadata and capabilities are not revoked after free. These issues can
be fixed by a capability aware malloc.
