Subject: [PATCH] kbuild: Restore .version auto-increment behaviour for Debian/RPM packages

Since 2df8220cc511 ("kbuild: build init/built-in.a just once"),
generating Debian packages using 'make bindeb-pkg' results in
packages that are stuck to the same .version, leading to unexpected
behaviours (multiple packages with the same version).

Restore the previous behaviour by calling init/build-version
instead of reading the .version file. This is likely to result
in too many .version bumps, but this is what was happening before
(although the bump was affecting builds made the current one).

Only tested with bindeb-pkg.

Fixes: 2df8220cc511 ("kbuild: build init/built-in.a just once")
