quote_path: optionally allow quoting a path with SP in it

Some code in wt-status.c special case a path with SP in it, which
usually does not have to be c-quoted, and ensure that such a path
does get quoted.  Move the logic to quote_path() and give it a bit
in the flags word, QUOTE_PATH_QUOTE_SP.

No behaviour change intended.
