Disable rpcbind.service and rpcbind.socket in presets

Issue

• On RHEL 9 and RHEL 10 systems, the rpcbind service is enabled and starts automatically after reboot due to the systemd preset provided by the RPM package.
• This occurs even when rpcbind is not required, including systems that use only NFSv4 mounts.
• This behavior conflicts with security hardening guidelines, which recommend not running unnecessary RPC services.
• There is no need to activate RPCbind through a preset.
