cmdutil: use crecordmod.checkcurses
Instead of blindly trusting the user's experimental.crecord, we use checkcurses
to abstract that logic so that we can handle the case where python was not
built with curses.
Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
