vzctl: skip setting meminfo on a vswap-enabled CT

It does no harm to try setting meminfo on a vswap-enabled container,
since it is ignored by kernel anyway. The only problem is somewhat strange
message:

	Configuring meminfo: 9223372036854775807

Avoid this by checking if CT config is vswap-enabled, and skipping meminfo
configuration if it is.
