[Buildroot] [PATCH] support/scripts/pkg-stats: extract current commit id, not master

[Thomas Petazzoni]

pkg-stats extracts the Buildroot commit id from which the package
information was collected. However, when doing so, it always assumes
we're using the master branch, by running "git log master".

But in fact, pkg-stats can be run from any branch/tag, so it makes a
lot more sense to use "git log HEAD".

As was discussed with Baruch and others, the page at
http://autobuild.buildroot.net/stats/ now shows the results
corresponding to the next branch when such a branch exists. However,
the commit ID currently shown at the bottom of the page is incorrect,
as it shows the one of the master branch at the time the page was
generated.
