Subject: [PATCH v2] kbuild: (bin)rpm-pkg: fix version number handling

The "Release:" field of the spec file is determined based on the
.version file.

However, the .version file is not copied to the source tar file.
So, when we build the kernel from the source package, the UTS_VERSION
always indicates #1. This does not match with "rpm -q".

The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either.
Please note the kernel has already been built before the spec file is
created. Currently, mkspec invokes mkversion. This script returns an
incremented version. So, the "Release:" field of the spec file is
greater than the version in the kernel by one.

For the source package build (where .version file is missing), we can
give KBUILD_BUILD_VERSION=%{release} to the build command.

For the binary package build, we can simply read out the .version file
because it contains the version number that was used for building the
kernel image.

We can remove scripts/mkversion because scripts/package/Makefile need
not touch the .version file.

$(cat .version||echo 1)"

.version might not exist at that point - for example when calling
make rpm-pkg from a pristine source tree. Apart from that looks good
to me.
