This speeds up parallel unit test runs from a very consistent 2:49 to
a very consistent 1:53, or a 33% reduction.

This is useful when you have multiple versions of the same gem installed. It can be leveraged like so:
```
describe gem('rest-client') do
its('versions') { should include /1.8\.\d+/ }
its('versions') { should include /2.0\.\d+/ }
its('versions.count') { should_be eq 2 }
end
```

The gem resource used to determine if a gem is installed based on the exit
status of the `gem` command, however that command will return zero
if the package was found or not. This patch checks to ensure that the
`gem list` command actually includes the gem name or is empty to
determine if the gem is in fact installed.
If the gem command returns something other than a `0` exit code, then
it'll skip the resource.

RubyGems on windows comes with a batch file that wraps the `gem` command
so it executes correctly. This change uses that batch file for windows
for our `gem` resource, and also properly handles when we receive no output
from the command.
