kbuild: version.h should depend on .kernelrelease

Rebuilding a previously built tree while using make's -j options from time to
time results in the version.h check running at the same time as the updating
of .kernelrelease, resulting in UTS_RELEASE remaining an empty string (and as
a side effect causing the entire kernel to be rebuilt).
