[Buildroot] [PATCH 0 of 4 v2] Add POST_RSYNC hook

[Thomas De Schampheleire]

This patch series adopts the POST_RSYNC hook patch by Tzu-Jung Lee and
changes the default rsync exclusion list, as discussed on the Buildroot
developer days.
The other rsync-related patch submitted by Tzu-Jung Lee (custom rsync
command) should not be needed anymore as its use case is covered by
the second patch in this series.
