[PATCH OSSTEST] mg-list-all-branches: Sort branches according to any embedded version

[Ian Campbell <ian.campbell@citrix.com>]

Many of our branches include a version number, this change results in
e.g. linux-3.0 < linux-3.4 < linux-3.10 rather than linux-3.0 <
linux-3.10 < linux-3.4, which is more natural for uses such as
./mg-all-branch-statuses.

Requires Sort::Versions (Debian package libsort-versions-perl).
