Subject: Keep LC_*, LANG, set default LC_CTYPE


Python 3.6 and earlier Python 3 require a correctly configured locale to
support non-ASCII values for file names and other parameters. Certmonger
now passes down LANG and LC_* env vars. It also sets LC_CTYPE=C.UTF-8 as
default in case no LC_CTYPE is set.
