Bug description:
  [Impact]
  With a recent update of python from 3.5.1 to 3.5.2, the pathlib.Path.path property is gone. This impacts MAAS as it will cause it to fail importing SSH keys, which prevents users from deploying.

  [Test Case]
  1. Install MAAS
  2. Import SSH Key (example, maas maas sshkeys create key="$(ssh-add -L | grep lee.trager@xxxxxxxxxxxxx)")

  With fix - The key will be imported correctly.
  Without fix - The key will fail to import.

  Work around sudden loss of pathlib.Path.path property in Python 3.5.2
  release.

  [Regression Potential]
  None. Tested and proved that using the different path fixes the issue.

  == Original bug report ==
  When I add a public SSH key over the API or in the UI I get the following error

  $ maas maas sshkeys create key="$(ssh-add -L | grep lee.trager@xxxxxxxxxxxxx)"
  {"key": ["Invalid SSH public key: 'PosixPath' object has no attribute 'path'"]}

  This was introduced in 5118 in the validation code of SSH keys but
  appears to be exposing a bigger bug. If you run ./bin/test.rack
  src/provisioningserver/utils/tests/test_sshkey.py the tests fail. I'm
  guessing that something is mocking check_output in a previous test and
  not unmocking it.
