kernel-build: fix STRIP_KERNEL_EXPORTS for 64-bit kernels
While parsing the nm output, we need to account for the fact that 64-bit kernels
have 64-bit wide addresses. While at it, replace the grep | sed combo with a
single awk invocation and a stronger regex.

STRIP_KERNEL_EXPORTS for recent kernels"
