[Buildroot] [PATCH next 3/5] support/scripts/pkg-stats-new: add current version information

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

This commit adds a new column in the HTML output containing the
current version of a package in Buildroot. As such, it isn't terribly
useful, but combined with the latest upstream version added in a
follow-up commit, it will become very useful.
