Make pip dry run work better for the common case

This change allows the pip module to figure out if something needs to be done during
a dry run using 'pip freeze'. This is implemented for the most basic case: name,
version and state=(present|absent). In other cases it will fall back to the old
behavior.
Setup module: Additional facts when using ansible with Linux on System z

- Improved parsing of /proc/cpuinfo to take the specifics of Linux on
System z. ansible_processor and ansible_processor_cores are now
completed.
- Also improved virtualization facts in the same environment, parsing
the output of /usr/bin/lscpu to populate virtualization_type and
virtualization_role more precisely. If lscpu is not available, then
stick to the previous behavior.

The apache2_module module did not properly handle when a2enmod would
handle apache module dependancies.  It would always return a state of
changed.  I've updated the regular expression to properly parse that
output as well as the normal output.  A good example of this is the
mod_proxy_http module.
