CLI: add talloc leak report, controlled by an environment variable.
The argument handling in notmuch.c seems due for an overhaul, but
until then use an environment variable to specify a location to write
the talloc leak report to. This is only enabled for the (interesting)
case where some notmuch subcommand is invoked.
