ec2 module: Delay instance tagging to later in the instance creation process

In check mode if a symlink does not exist there is no need to check the ownership properties (which causes an exception)

Fixes #7828

Tagging recently created instances can result in
InvalidInstanceID.NotFound errors.

By delaying the tagging until the last part of instance creation,
we should be typically more fortunate (avoiding all such race
conditions might need more work)

Fixes #7760

Fixes #7812

Merge branch 'unarchive-fix-7777-simple' of https://github.com/toddmowen/ansible into toddmowen-unarchive-fix-7777-simple

The new CentOS 7 beta lists the distribution as "CentOS Linux", which
breaks the distribution detection and class loading. This patch fixes
that by taking just the first entry in the string when a space is
detected.

Allow gem executable to contain spaces

Virtualenv's activate script sets the VIRTUAL_ENV environment variable to the path of the virtualenv. Checking this variable is a reasonably common way to verify that execution is happening in a virtualenv. It would be convenient if this module's virtualenv handling set this environment variable.

Allow npm executable to contain spaces

rbenv has a special exec function which loads the correct ruby version before executing a command.
The syntax for this is `/usr/local/rbenv/bin/rbenv exec gem ...` for example.
But previously when specifying executable='/usr/local/rbenv/bin/rbenv exec gem' this would not work because the string was treated as one executable. This PR fixes that by splitting the executable on spaces.
