[PATCH] efi_runtime: fix the broken kernel vermagic when upgrading the kernel pacakge (LP: #1223801)

[Keng-Yu Lin]

Using `uname -r` in the Makefile, the compiled .ko has the vermagic of the
current running kernel, rather than the upgrading one.

The correct way is to use the $kernelver variable provided by DKMS.
