m68k: defconfig: Update defconfigs for v6.3-rc1

- Drop CONFIG_IP_NF_TARGET_CLUSTERIP=m (removed in commit
    9db5d918e2 ("netfilter: ip_tables: remove clusterip target")),
  - Enable modular build of the Kerberos V mechanism for Secure RPC
    (auto-builtin since commit dfe9a12345 ("SUNRPC: Enable
    rpcsec_gss_krb5.ko to be built without CRYPTO_DES")),
  - Enable modular build of the new Dhrystone benchmark test,
  - Drop accidental enablement of CONFIG_PCCARD=y in multi_defconfig.
