MINOR: init: make -cc support environment variables expansion

I found myself a few times testing some conditoin examples from the doc
against command line's "-cc" to see that they didn't work with environment
variables expansion. Not being documented as being on purpose it looks like
a miss, so let's add PARSE_OPT_ENV and PARSE_OPT_WORD_EXPAND to be able to
test for example -cc "streq(${WITH_SSL},yes)" to help debug expressions.
