virsh is reporting ppc64le and not ppc64

[Mike Rushton]

MAAS version 1.8.2+bzr4041-0ubuntu1~trusty1 from maas-maintainers stable PPA
IBM_PowerKVM release 3.1.0 gold build 41.0 (pkvm3_1_0)

Upon trying to enlist & commission a kvm VM on PowerKVM host, virsh is reporting ppc64le to MAAS as opposed to ppc64el.

This is tripping up probe-and-enlist-hardware:

The manual fix is to add the following line to /usr/lib/python2.7/dist-packages/provisioningserver/drivers/hardware/virsh.py under ARCH_FIX

'ppc64le': 'ppc64el',

Mike, when you're testing 1.9, if you can verify that 1.9 resolves this issue, we can remove the blocker tag for this bug.
