The stringid.TruncateID utility is used to provide a consistent length
for "short IDs" (containers, networks). While the dummy interfaces need
a short identifier, they use their own format and don't have to follow
the same length as is used for "short IDs" elsewhere.
In addition, stringid.TruncateID has an additional check for the given
ID to contain colons (":"), which won't be the case for network-IDs that
are passed to it, so this check is redundant.
This patch moves the truncating local to the getDummyName function, so
that it can define its own semantics, independent of changes elsewhere.
