Subject: [PATCH] Version changes for linux-surface debian package

Rename debian kernel packages so that they do not contain the full version
in the name any more as this allows automated updates via a package
repository. Instead the package name now only contains the $LOCALVERSION
string.

Also rename libc-dev to allow multiple versions to co-exist in the same
repository.
