* 'fix_depreciation_warning' of https://github.com/bbuchalter/rubyzip:
Use default ruby behavior for Array.join
Remove OUTPUT_FIELD_SEPARATOR-related test behaviors
Set OUTPUT_FIELD_SEPARATOR to nil in test
Prefer OUTPUT_RECORD_SEPARATOR to $\
Prefer OUTPUT_FIELD_SEPARATOR to $,
Since we are using the default behavior of OUTPUT_FIELD_SEPERATOR
anyway, let's allow Ruby to maange that default for us, so if it should
change in the future, we don't have to change.
