[rancid] exos.pm: patch to gather stack information

[James Andrewartha]

Hi,

The patch below adds extra parsing to ShowVersion in exos.pm, to print
out the individual device serial numbers, bootrom and image version.
Mostly I wanted the serial number, since the others are normally the
same across a stack.

Here's two examples of output, for a standalone switch, and a stack:

#Switch: Serial 1638N-41359, BootROM 1.0.1.8, IMG 22.6.1.4

#Slot-1: Serial 1637N-41621, BootROM 1.0.1.8, IMG 22.6.1.4
#Slot-2: Serial 1638N-41448, BootROM 1.0.1.8, IMG 22.6.1.4
#Slot-3: Serial 1638N-41354, BootROM 1.0.1.8, IMG 22.6.1.4
#Slot-4: Serial 1638N-41318, BootROM 1.0.1.8, IMG 22.6.1.4
#Slot-5: Serial 1638N-41357, BootROM 1.0.1.8, IMG 22.6.1.4

This patch might be fuzzy since I generated it against upstream but I'm
running 3.9-1~bpo9+1 from Debian. Also I only have X440-G2s to test against.
