virsh: Improve virsh manual for virsh memtune command

Browse Source 
Commit 0a22f54 added --min-guarantee option for the memtune command.
This option is supported only by the ESX hypervisor. This patch adds a
statement about this fact, to prevent user confusion.

This patch also adds explanation how to clear/set to unlimited the
memory tunables. (documments the -1 value).
