runtime: avoid panic on metrics gathering

Browse Source 
While running with a remote hypervisor, whenever kata-monitor tries to access
metrics from the shim, the shim does a "panic" and no metric can be gathered.

The function GetVirtioFsPid() is called on metrics gathering, and had a call
to "panic()". Since there is no virtiofs process for remote hypervisor, the
right implementation is to return nil. The caller expects that, and will skip
metrics gathering for virtiofs.

Fixes: #9826
