Subject: Make tests work with Python 3.8 (#139)

* Make DistroChecker test work with Python 3.8

In Python 3.8, `platform.linux_distribution` has been removed. This was
anticipated, and the cloud-init code uses its own
`util.get_linux_distro` instead, which works fine w/o
`platform.linux_distribution`. However, these tests still try to mock
the platform function, which fails if it doesn't exist (Python 3.8).
Instead, mock the new function here, as this is a test for code that
depends on it rather than the function itself.

* Make GetLinuxDistro tests work with Python 3.8

In Python 3.8, `platform.dist` was removed, so allow mock to create the
function by setting `create=True`.

* Make linter happy in Python 3.8

Suppress E1101(no-member) as this function was removed.
