confd: sort interfaces according to length and name

A list of interfaces: x10 x9 x8 x7 x6 x5 x4 x1 x2 x3 should be sorted in order with x10 last. This hack accounts for the length that a regular 'sort -n' would otherwise generate: x1 x10 x2 ... This way we can ensure that the order of bridge ports is natural and what end users expect. Signed-off-by: Joachim Wiberg <[email protected]>
