ensure all strings pulled out of ENV are UTF8 on windows

Browse source 
strings assigned to LogStash::Event fields must be UTF-8 and
since most windows aren't UTF-8 by default we must intercept all
get operations and convert the strings to UTF-8. Issue surfaces in
logstash-filter-environment, for example.

Fixes #2666
