linux-image: Include package version in utsname version string (Closes: #638878)

There is not enough space for both timestamp and package version, so
replace the timestamp by setting KBUILD_BUILD_TIMESTAMP.

We now need to get the distribution name in debian/rules.real, but
we already have DISTRIBUTION as the suite name so use DISTRIBUTOR for
the distribution name (!).

The utsname version string also appears in /proc/version and the init
banner, so don't bother including it again explicitly.  This means we
no longer need to patch init/version.c and scripts/mkcompile_h at all.
Instead, split maintainer at the '@' and set KBUILD_BUILD_USER and
KBUILD_BUILD_HOST accordingly.

Carry on generating <generated/package.h>, but drop the parentheses
from LINUX_PACKAGE_ID now that it's not used in init/version.c.

Drop support for version.$DISTRIBUTION files.  Any derived
distribution can set KBUILD_BUILD_* in the same way we are doing.

+Subject: Add header file with package version information
+Date: Tue, 24 Jul 2012 02:15:43 +0100
 
 For distribution binary packages we assume
-$DISTRIBUTION_OFFICIAL_BUILD is set.  Add $DISTRIBUTION and
-$DISTRIBUTION_VERSION after the kernel version (UTS_RELEASE), and
-replace the account name used to build the package with
-$DISTRIBUTION_UPLOADER.
-
-[bwh: Changed $DISTRIBUTION_UPLOADER to $DISTRIBUTION_MAINTAINER.]
+$DISTRIBUTION_OFFICIAL_BUILD, $DISTRIBUTOR and $DISTRIBUTION_VERSION
+are set.
 
-For custom packages built from a linux-source package, read the
-package version from version.$DISTRIBUTION and add that after
-the kernel version string.
