Do switch to apt if aptitude is not installed (#30738)

Browse source 
Trying to use the apt module on a freshly install 16.04 Ubuntu VM with
"ansible -m apt -a 'name=* state=latest' all" fail with this backtrace:

  Traceback (most recent call last):

It seems that since aptitude is not installed on Xenial, so APTITUDE_CMD is None
and we later hit the bug in the upgrade function since it assume APTITUDE_CMD
is set.
