[PATCH] scripts: Fix incremental build header re-generation

[Jeevan Shriram <jshriram@codeaurora.org>]

compile.h and autoconf.h are ignored when checking headers sha as they
are always re-generated for every kernel compilation. However,
these two headers are packaged into kheaders tar. During incremental
compilation of kernel, kheaders tar file is always generated and re-packaged
irrespective of the changes in headers.
