Bug#219503: choose-mirror broken for manual entry

If you run choose-mirror and try to "enter information manually", it
doesn't work.  Used to work until recently.

The problem is in choose-mirror.c, where choose_country() ends with:

	country = strdup(debconf->value);
	debconf_set (debconf, DEBCONF_BASE "country", country);

Then in choose_mirror(), it does:

	manual_entry = ! strcmp(debconf->value, "enter information manually");

but by this time, debconf->value has been set to "value set", so the
compare always fails.
