[PATCH v2 2/2] submodule: don't print status output with ignore=all

["brian m. carlson" <sandals@crustytoothpaste.net>]

git status prints information for submodules, but it should ignore the status of
those which have submodule.<name>.ignore set to all.  Fix it so that it does
properly ignore those which have that setting either in .git/config or in
.gitmodules.

Not ignored are submodules that are added, deleted, or moved (which is
essentially a combination of the first two) because it is not easily possible to
determine the old path once a move has occurred, nor is it easily possible to
detect which adds and deletions are moves and which are not.  This also
preserves the previous behavior of always listing modules which are to be
deleted.
