This will return whether the path passed in as arg is part of a local file system or a remote
file system. This method is mainly used by the DiskCapacityMonitor thread and we don't want
to monitor remote fs available space as due to network problems/firewall issues the call to
getUsableSpace can hang. See bug #49155. On platforms other than Linux this will return false
even if it on local file system for now.
