If a gemspec has UTF-8 characters in it, ruby will fail loading it with
invalid multibyte char (US-ASCII)
This change forces the encoding to be correct, we assume everyone now
uses UTF-8.
bundler for example needs to have the GEM_HOME being passed trough to
function properly.
For gems that are loading content dynamically, or can use plugins, use
buildRubyGem.
For executables that are wrapped in their own sealed thing use
bundlerEnv.
lib.escapeShellArgs doesn't work well when a null value is provided.
[] is also the correct value since it's really just an empty list of
arguments that we have.
