Subject: [PATCH] fix(build): set KBUILD_BUILD_VERSION to silence missing
 .version warning

The build process deletes linux-6.12.68/.version before invoking the
kernel build, but the x86 boot banner later tries to read it to print
the build number. This caused a stray "cat: .version: No such file or
directory" warning and left the banner rendering as "(#)" with no
number.

Setting KBUILD_BUILD_VERSION=1 provides an explicit build version so
the banner prints "(#1)" and the warning is suppressed.
