sysinfo: expose new API

The new virConnectGetSysinfo() API allows one to get the system
information associated to a connection host, providing the same
data as a guest that uses <os><smbios mode='host'/></os>, and in
a format that can be pasted into the guest and edited when using
<os><smbios mode='sysinfo'/></os>.
