android-tools: refresh patches with devtool

* devtool isn't able to regenerate them completely, it generates only
  top level commit which says that submodules were changed, like this:
  From c8fa114325e4e532657499b9bb6fd23cb6536eaa Mon Sep 17 00:00:00 2001
  From: OpenEmbedded <oe.patch@oe>
  Date: Tue, 2 Oct 2018 16:46:55 +0000
  Subject: [PATCH] Committing changes from do_patch

  ---
   external/libselinux | 2 +-
   system/core         | 2 +-
   system/extras       | 2 +-
   3 files changed, 3 insertions(+), 3 deletions(-)
  ..

  but it still creates relatively good commits in each submodule and
  after small manual cleanup they can be exported with
  git format-patch --no-numbered --no-signature

* rename .gitignore to prevent git ignoring the changes in .patch files
  in meta-oe already (we want to use it only later during the build)
