[rancid] [PATCH]: Improved IOS XE detection in rancid

[Alan McKinnon]

Cisco appear to have changed the IOS-XE stamp in "show version" for some
images. This causes the XE detection in ShowVersion() to fail, causing
the filtering for tracelog in DirSlotN() to not be applied.

One-line patch below. The strings are subtlety different, it seemed
easier to add a new regex rather than adapt the existing one.

Sample version output:

#show ver
Cisco IOS XE Software, Version 03.10.02.S - Extended Support Release
Cisco IOS Software, ASR1000 Software (X86_64_LINUX_IOSD-UNIVERSALK9-M),

Thanks. I forgot to mention my original patch applies to 2.3.8
