[Buildroot] [PATCH 01/11] support/scripts/pkg-stats: store latest version in a hash

[Heiko Thiery <heiko.thiery@gmail.com>]

This patch changes the name and the variable from latest_verion of type list
to rm_status of type hash. This is for better readability/usability of the
data. With this the json output is more descriptive.
