Make Missing Modules.symvers Fatal

Detect early on in configure if the Modules.symvers file is missing.
Without this file there will be build failures later and it's best
to catch this early and provide a useful error.  In this case the
most likely problem is the kernel-devel packages are not installed.
It may also be possible that they are using an unbuilt custom kernel
in which case they must build the kernel first.
