spec: do not recompute the build-id of vmlinux

Browse Source 
Since rpm-build version 4.14.0-rc1(commit id: 4842adf), the new code
will recompute the build-id of vmlinux when generating debuginfo, and
results that the build-id is different from the boot image. Some debug
tools, like perf, when we use `-k` to specify vmlinux, it would refuse
to load vmlinux while detecing the build-id is different between vmlinux
and the current boot image.

We can use `$ file vmlinux` or `$ objdump -s -j .notes` to check
vmlinux's build-id, and `$ hexdump /sys/kernel/notes` to check current
boot image build-id.

This patch is prevent build-id changing from generating debuginfo
package.
