Subject: [PATCH] kbuild: setlocalversion: ignore private tags while reporting local version

The output 'git describe' is relative to the immediate preceding tag.
When the immediate tag preceding the HEAD is a private tag,
setlocalversion extracts information with respect to the private tag and
wrongly reports them with respect to Linux tag.

Fixing this to extract information with respect to Linux tags.
