[Buildroot] [PATCH 1/2] package/docker-engine: security bump to version 18.09.7

[Peter Korsgaard <peter@korsgaard.com>]

Fixes CVE-2018-15664: API endpoints behind the 'docker cp' command are
vulnerable to a symlink-exchange attack with Directory Traversal, giving
attackers arbitrary read-write access to the host filesystem with root
privileges, because daemon/archive.go does not do archive operations on a
frozen filesystem (or from within a chroot).

And includes additional post-18.09.6 fixes:

Builder
- Fixed a panic error when building dockerfiles that contain only comments.
  moby/moby#38487
- Added a workaround for GCR authentication issue. moby/moby#38246
- Builder-next: Fixed a bug in the GCR token cache implementation
  workaround.  moby/moby#39183

Runtime
- Added performance optimizations in aufs and layer store that helps in
  massively parallel container creation and removal.  moby/moby#39107,
  moby/moby#39135
- daemon: fixed a mirrors validation issue. moby/moby#38991
- Docker no longer supports sorting UID and GID ranges in ID maps.
  moby/moby#39288

Logging
- Added a fix that now allows large log lines for logger plugins.
  moby/moby#39038
