veyron/tools/mounttable: defaulting mounttable name to "" if unspecified for Glob
Globbing the default mounttable (at defaultNamespaceRoot) is a common task.
Currently, one has to run: ./mounttable glob "" "..." because the mounttable
name argument is required. This CL makes it optional, defaulting it to "".
